Ultimate Guide to Zinc Coated Rotors for Your Vehicle

For enthusiasts and drivers, zinc-coated rotors have become important due to their exceptional performance and durability. This ultimate guide seeks to provide readers with a comprehensive outlook on zinc-coated rotors by exploring their manufacturing process and benefits and comparing them with traditional rotors. Throughout this article, we will look at why these brakes are an excellent choice for better braking, less corrosion, and longer brake life, making upgrading your current set-up or understanding what they mean necessary.

What are Zinc Coated Rotors?

zinc coated rotors

On the other hand, zinc-plated rotors, are a type of brake rotor that has been treated with a layer of zinc to improve its resistance against rusting or getting worn out. Galvanizing is done in this protective coating, enabling the brake rotors to resist harsh environmental conditions such as moisture and road salts that cause rusting. Therefore, besides protecting the surface of the rotor, the coating improves general braking capability through increased heat dispersal. They have been recognized for their extended life cycles compared to cast iron conventional rotors, reducing maintenance costs and making them an attractive option among automobile enthusiasts who want reliable brakes for their vehicles.

Understanding the Benefits of Zinc Coating

According to my findings from the top ten automotive maintenance platforms available online, there are several pros associated with using zink coating in making brake rotors. Firstly, corrosion resistance is one significant advantage; since there is a thin coat of zink, it works like armor against water and salt used for roads, thereby reducing the chances of rusting into materials that form parts of cars. Areas prone to freezing winters or located near oceans where humid weather increases salinity levels tend to attack uncoated metal more frequently than others do.

Another benefit I learned about is enhanced heat dissipation, crucial for maintaining braking performance. The zinc layer can tolerate more heat, thus preventing brake fade during high-performance driving situations. Among technical parameters are indicated specific features such as the typical thickness of the zink layer, ranging from 10 to 20 microns, and durability in extreme conditions where zinc-coated rotors can be up to 50% more long-lived than those without it.

Also, when considering maintenance, these breaks are preferable since they tend to last longer and require fewer changes, which means that the owner will save time and money. By all accounts, zinc-coated rotors come across as a sturdy and effective solution for anyone who wants to improve their ride’s braking system while ensuring its endurance and better performance.

How Do Coated Rotors Differ from Standard Rotors?

Through my exploration of various automotive maintenance sites, it became evident that zinc-coated rotors differ significantly from standard rotors in multiple aspects. First of all, there is a primary difference between these two types in terms of corrosion resistance. Unlike normal ones prone to rusting, zinc covering protects them against moisture or other corrosive agents.

Zinc-coated rotors are more effective at heat dissipation. During heavy braking, they can withstand higher operating temperatures, which is crucial to avoid brake fade. To indicate that these rotors offer greater thermal management, one only needs to look at their ability to deliver performance even at temperatures exceeding 400°C, unlike the non-coated ones that start deteriorating in comparable conditions.

Other than this, zinc-coated rotors are also impressive in terms of durability since they last up to fifty percent longer than default ones. This duration is between thirty thousand miles and sixty thousand miles, depending on how often a driver uses or abuses them. This thickness should be considered as it remains within the acceptable range of 10 to 20 microns, hence not affecting the overall structural soundness of the rotor. In summary, these technical criteria provide enough evidence for investment into ZINC-COATED ROTORS for those who wish to prolong their braking systems’ lifespan and improve their efficiency.

Typical Applications of Zinc-Coated Brake Rotors

From my research across major car maintenance websites, I found that zinc-coated brake rotors are common across many different kinds of cars and driving conditions. They work well with high-performance vehicles which require extra braking power. Moreover, they are used in vehicles that operate in harsh environments, such as regions with a lot of rainfalls or frequently driven coastal areas due to their rust-fighting characteristic given by the zinc layer.

Technically speaking, I had noted some main explanations behind it:

• Resistant to corrosion: The zinc coating offers sufficient protection against rust, thereby elongating the life span, especially in hard environments.
• High heat: Even when subjected to intense braking, they still perform well until the temperature reaches 400 degrees Celsius (about 7500 degrees Fahrenheit).
• Longevity: These rotors’ lifespan ranges between thirty thousand and sixty thousand miles, making them fifty percent stronger than standard rotors. Thus, they are a much cheaper option in the long run.

This selection of features will attract those drivers who want to ensure efficient braking systems that will last longer and provide better performance and reliability.

By collapsing data extracted from the top 10 websites and aligning real-life experiences with technical specifications, I am now able to decide which zinc-coated rotors may work best on my car.

Zinc Coated Drilled And Slotted Rotors – Instruction Manual

When it comes to mounting zinc-coated drilled and slotted rotors, I ensure that I have all the appropriate tools and a clean workspace. Firstly, the vehicle is safely lifted, and the wheel is detached. After that, I separate the caliper from the bracket supporting it so as not to stress the brake line. Consequently, I eliminate former rotors watching out for any retained screws.

Then, I meticulously cleanse the hub surface to make it flat for new rotors. Following that, the new zinc-coated drilled and slotted rotors are set by lining up and securing them on the hub. Thus, after this step, all bolts are torqued according to the manufacturer’s specifications on caliper brackets and re-attached properly in sequence, which will not result in rotor warping. Lastly before putting back the wheel, I should again examine if brake components are properly aligned and functioning normally under no load conditions of a car. This approach helps maintain the proper performance and longevity of the brake system.

Tools Required For Installation

In installing a new set of zinc-coated drilled and slotted rotors with insight from leading automotive repair websites, a careful selection of key tools is necessary, depending on their contributions to success. The following tools will be needed:

1. Jack: Hydraulic or floor jack (support used for lifting vehicle)
2. Jack Stands: Once the car has been lifted up, it provides support so that one can work under it without fear of collapse.
3. Lug Wrench: Used for loosening or tightening lug nuts on wheels, it allows easy wheel replacement.
4. Torque Wrench: To put correct torque specification on lug nuts so they do not over-tighten but at the same time remain tight enough tool use-wise when doing good fastening jobs.
5. Screwdriver Set: Various screwdrivers could be required to remove screws holding brackets and calipers.
6. Hammer: Instances may arise where I have to gently tap the rotor when it is stuck using non-marring hammers or rubber mallets.
7. Brake Cleaner: So that the braking system won’t be obstructed by any dirt, components need to be cleaned before their installation.
8. Gloves and Safety Goggles: Personal protective equipment is essential in such cases when working on a vehicle under any circumstance.
9. Pry Bar: This tool can help me remove the rotors with care when required.
10. Measuring Tools: Use calipers or measuring tape to check if the new rotors meet the specifications necessary for each type of car.

Given these tools and step-by-step instructions from reliable automotive sources, I can install my rotors safely and effectively.

Step-by-Step Installation Process

1. Preparation: To start, I gather all of the necessary tools and safety items. Clearing my workspace of clutter and ensuring it is well-lit helps reduce accidents and tool misplacing.
2. Lifting the Vehicle: Using a hydraulic jack, lift the car up and rest securely on jack stands to hold it stable before starting with anything else.
3. Removing the Wheel: With a lug wrench, loosen lug nuts in a star pattern so pressure is applied equally around them. The wheels should then be removed after they have been completely loosened from their threads.
4. Accessing the Brake Components: Unbolt or unscrew the caliper with a screwdriver set. Then, slide the caliper onto one side gently without putting tension on the brake line.
5. Removing the Old Rotor: Whenever the rotor is stuck, I use a pry bar to gently free it. Then, I examine it for wear and debris.
6. Cleaning Components: To prevent dust or contaminants from affecting performance, I spray brake cleaner on the new rotor and other components. It is very important that these parts are clean so as not to have braking issues.
7. Installing the New Rotor: The new rotor is placed on the hub, making sure it is fixed properly.
8. Reinstalling the Caliper: With caliper in place, i fix it again ensuring i use torque wrench to tighten it to specified torque, which usually ranges between 20-25ft-lbs but I always confirm with specific vehicle’s manual.
9. Reattaching the Wheel: When reattaching the back wheel, after tightening the lug nuts by hand, I first use a lug wrench in a star configuration up to the vehicle maker’s recommended ft-lbs range of 75-100, based on make and mode.
10. Final Checks: Before lowering the vehicle down, I remove all tools from beneath it and ensure that every bolt and nut has been tightened correctly and that the brake parts are functioning well.

To efficiently replace brake rotors and ensure that vehicles’ performance is dependable yet safe requires observance of these steps and following the advice of trustworthy automotive sources.

Common Mistakes to Avoid During Installation

1. Neglecting to Check Brake Fluid: In many cases before starting installation activities i will remember checking how much fluid remains in brake. Low fluid levels could cause air inside their lines, hence brake failure. This helps maintain system integrity by keeping an eye on fluid levels
2. Forgetting to Torque to Specifications: Another mistake that frequently occurs involves not following the manufacturer’s specifications regarding torques during the reinstallation of calipers or wheels. Within no time, such things may lead to uneven wear or loosening of parts. I always check the specific vehicle’s manual for correct torque settings. Normally, caliper bolts should be around 20-25 ft-lbs while lug nuts should be tightened at 75-100 ft-lbs
3. Improper Rotor Orientation: I must ensure proper orientation when installing the rotor, especially for directional rotors. When put in the wrong direction, they result in unproductive brakes. It is important to check for markings on the rotor indicating proper installation direction.
4. Skipping Cleaning of the Hub: Sometimes I forget or do not sufficiently clean new rotors before putting them on hub surfaces well. This can cause vibrations as well as uneven wear later if there is any debris or rust that hinders rotor seating. To get optimal performance, a surface must be clean and smooth.
5. Ignoring Break-In Process: I usually overlook the initial break-in (or “bedding”) procedure for new brake pads and rotors after installation. This ensures appropriate contact and performance; hence I strictly adhere to such instructions provided by manufacturers to achieve maximum braking efficiency during this process.

Being aware of these common mistakes makes me more confident in performing a successful brake rotor installation that ensures both safety and top vehicle performance.

How to Keep Zinc-Coated Brake Rotors in Good Condition?

Zinc-coated brake rotors require proper maintenance to ensure they last long and achieve the best performance. The following are key maintenance tips:

1. Regular Cleaning: It is important to clean the rotors regularly using a recommended brake cleaner to avoid corrosive buildup. This helps eliminate dust, debris, and other foreign materials that might cause rusting and wear out.
2. Inspect for Damage: Check the rotors regularly for signs of wear, warping, or damage. Early detection can prevent bigger problems and improve overall braking performance.
3. Monitor Pad Wear: Beware of worn-out brake pads, which could be generating too much heat on the rotors. Replacing pads when necessary helps preserve zinc-coating integrity.
4. Avoid Excessive Heat: While driving, avoid constant hard braking, which causes rotor discs to overheat. Instead, try engine braking where possible to reduce stress on the brake system.
5. Storage Considerations: If you’re going to put your vehicle away for a lengthy period, consider applying a protective coating to the rotor surfaces to avert moisture accumulation, which can lead to rust formation.

By following these simple maintenance tips, one can lengthen the lifespan of his zinc-coated rotor brakes while maintaining effective brakes throughout the operation.

How Do I Clean Zinc Coated Brake Rotors?

Cleaning zinc-coated brake rotors is easy, but I always do it cautiously to avoid damaging their protective layer. According to top automobile resources, here’s how I go about it;

1. Gather Materials: Before starting, I ensure I have bought quality break cleaners and gloves. I also carry a soft brush and lint-free clothes with me, which protects my hand from being hurt.
2. Safety First: When cleaning my car’s brakes, I apply emergency brakes first, then use wheel chocks, and keep checking whether any movement is taking place in order not to cause accidents.
3. Inspect First: I must check the brake rotors for any obvious damages or wears. This will help me know if further action is needed through preliminary inspection.
4. Apply Brake Cleaner: Therefore, when I apply a brake cleaner to the rotor surfaces, this helps penetrate any buildup of dirt. Most sources advise using cleaners that do not contain harsh solvents, which can damage the zinc coating.
5. Use a Soft Brush: After the cleaner has been on for about a minute, I gently scrub off all the dirt and dust that might be stuck on it. We are cautioned against using abrasive tools, which could destroy it.
6. Rinse and Dry: When I am done cleaning, I wipe them with a lint-free cloth to remove anything left behind. I do not rinse them with water because they could corrode, especially if they have a coated surface.
7. Final Inspection: Finally, before bringing back all brake components, I inspect them again to ensure their cleanliness without contamination.

This makes my zinc coated rotors last longer and function better.

Preventing Rust and Corrosion

I take some key measures, as informed by leading automotive maintenance websites, to avoid rusting and corrosion on my zinc-coated rotors.

1. Quality of products used: I ensure that the products I use, such as brake cleaners and lubricants, are meant for vehicles and do not contain chemicals that can ruin the zinc coating. It is common knowledge that professional brands in this field contain inhibitors against corrosion.
2. Proper installation: I carefully tighten all bolts to the factory-recommended specifications during reassembly to prevent undue stress on the rotor by bolting. Typically, torque specifications vary from 70lb-ft to 100 lb-ft, depending on a car model.
3. Protection of the environment: When my vehicle is most often exposed to salty roads and harsh weather, I put a thin coat of anti-corrosion spray on the surface of the rotor without affecting its braking performance. This spray will also serve as an additional barrier against moisture.
4. How they are stored: When my car needs to be parked for long periods of time, I prefer to store it in a dry place with controlled temperatures to lower the chances of rusting.

Adopting these guidelines will extend the useful life of my rotors while they maintain their rust-free condition and continue operating efficiently.

When Should You Replace Your Zinc-Coated Rotors?

I am going through several indicators taken from top auto maintenance websites which help me determine when my zinc coated rotors should be changed. Firstly, visible damage like cracks or warping heat-treated rotors may be visible, which negatively affect their efficiency. Also, I watch out for changes in thickness; if it wears off down toward the manufacturer’s minimum specification (which normally goes about 1mm less than the original thickness), then a replacement case should be considered. Furthermore, grinding noise or squeaking while slowing down might suggest worn-out lining or contamination, among other troubles, since it is not smooth anymore.

Similarly, a reduction in braking power or turbulence during braking shows that my rotors have almost finished their useful lives. Lastly, how frequently maintenance is done calls for straight brake pad replacements each time, which indicates ineffectiveness and demands new rotors. These factors help me ensure that my rotors are always working optimally and safely.

Advantages of Drilled and Slotted Brake Rotors

Whenever I want to improve my vehicle’s braking performance, I believe the drilled and slotted brake rotors have many advantages. What distinguishes these rotors is their unique design, which helps release heat more efficiently, thus minimizing brake fades during hectic drives. On top of that, such slots help sweep away dirt and water from the disk surface, enhancing both wet weather condition efficiency and consistent stoppage power. Additionally, perforated holes contribute to braking response by reducing weight without compromising strength. In summary, going for drilled or slotted ones enhances my confidence while breaking and improves safety and handling, thus making me fit for challenging driving experiences.

Boosting Braking Performance Through Drilled Rotors

When considering how to enhance braking using drilled rotors, I typically consider several critical technical aspects borrowed from reputable motoring pages. Age-old wisdom suggests that the diameter and thickness of the rotor must be considered; therefore, if possible, it is always best to go with a rotor with a diameter a little beyond or at least as large as your factory specifications since it maximizes braking leverage. Most performance drilled rotors come with diameters between 11-14 inches thereby providing greater area for heat dissipation.

Another issue is the material composition: I like high-carbon cast iron rotors specifically because they can remain stable thermally while providing the durability required here. Superior-quality materials are required since they reduce warping and prolong longevity; hence, one can argue this decision on reduced wear rates under extreme circumstances.

Moreover, I think of how many holes there are and how big each hole is: this correlates directly with airflow provision through air ducts, so that hot brakes may cool down quickly when necessary. Yet I make sure not too much, or else they will become weak structurally because there should be a balance between hole placements wherever possible. The number of holes can vary from 6 to 12 and their diameters are between 10 mm to 12 mm.

Brake pad compatibility is the last thing I consider using performance pads specifically designed for drilled rotors maximizes benefits and ensures good contact with the rotor surface, which enhances heat transfer. By considering these factors, I can significantly improve my braking system using drilled rotors.

Friction Management and Heat Dissipation through Slots

When discussing the effects of slots on braking performance, it becomes evident that they play a major role in friction management and heat dissipation. The following technical parameters have been culled from the web’s leading automotive sites:

1. Slot Configuration: The friction coefficient can be increased by increasing the contact area through slot design and arrangement. Most slot designs are either angled or curved because they result in better pad bite, especially during hard stopping.
2. Number and Size of Slots: Normally, it is advisable to have between four (4) and ten (10) slots, each about five (5) to eight (8) millimeters wide. Such a configuration optimizes airflow, clearing debris and gases generated by high-pressure braking conditions.
3. Material Durability: Just like with drilled rotors, using high-quality materials for slotted rotors ensures they can withstand the additional stresses imposed during braking. Because of their ability to resist wear and maintain structure, I usually prefer high-carbon or ceramic composite materials too much.
4. Managing Heat: The brake components can cool down with the increased surface area of the slots, decreasing the thermal fade during long braking sessions. I ensure that my chosen slots promote cooling without damaging the rotor’s strength.
5. Compatibility with Brake Pads: Slotted rotors work best with pads built specifically for slotted rotors which guarantee consistent contact and effective heat transfer. I always check pad material compatibility to maximize performance.

By considering these parameters, I’m able to get more out of slotted rotors in terms of friction and heat dissipation during braking.

Choosing Between Drilled, Slotted, or Coated Rotors

When deciding between drilled, slotted, or coated rotors, I’ve read top sites like CarandDriver to make an informed decision based on a variety of technical findings.

1. Friction Performance: Drilled rotors are great at dissipating heat and maintaining braking performance under even extreme conditions, but their design enhances pad bite in slotted rotors. Additionally, slotted rotors aid in clearing debris and gases; hence, they are preferred for aggressive braking situations.
2. Durability and Wear: For instance, coated rotors have improved corrosion resistance and are therefore suitable for daily driver cars, while high-carbon or ceramic composite materials used in drilled and slotted rotors enhance their life span when subjected to tough use.
3. Heat Management: Designed for better heat absorption capabilities at higher temperatures, it may crack due to extensive temperature changes. Unlike them, the slot design of some other models, such as drilling, prevents them from losing strength as much after being heated up many times because they cool off faster.
4. Brake Pad Compatibility: Matching brake pads with rotor type is critical. To ensure optimal performance and longevity I prefer pads designed explicitly for slotted or drilled rotors
5. Cost and Application: Lastly, application matters most. If it is track use or high-performance applications, I would go for either slotted or drilled rotors because they offer better heat management. On the other hand, for daily driving, coated rotors are a nice compromise that offers corrosion resistance and good durability.

Through these factors, I can effectively identify which rotor type is best suited to my braking performance and longevity requirements.

Other Rotor Types: Comparing Zinc-Coated Rotors

Several key factors emerge when comparing zinc-coated rotors to other rotor types. The addition of zinc to the rotors protects them from rust and corrosion, thus increasing their lifespan by a substantial margin compared to uncoated traditional rotors. This makes them perfect for vehicles operating in tough environments since they can keep their performance and appearance intact for a long time.

On the other hand, slotted and drilled rotors are better in performance because they have better cooling abilities and less brake fade when subjected to heavy loads. However, they do not offer the same amount of protection against rust as zinc-coated rotors. Therefore, while slotted and drilled rotors may be useful in high-performance situations, people who drive regularly may find it more convenient to use zinc-coated ones as such persons look forward to long-life brakes.

In essence, a choice between zinc-coated rotors and others is based on what an individual requires—either improved performance during aggressive driving or durability and resistance to corrosion for long-term maintenance.

What Is the Difference Between Zinc-Plated Vs. Zinc Zinc-Coated Rotors?

While the terms ‘zinc plated’ and ‘zinc coated’ may sound similar; it is crucial to note that these words refer to different processes/attributes involved. I have researched some top automotive websites, and I found out that most of the time, galvanization simply involves putting a thin layer of cover made of metal called zinc on a steel rotor through an electroplating process. It improves the visual finish and enhances its corrosion resistance capability, but it is relatively superficial and hence could wear away with time, especially under severe driving conditions.

Alternatively, zinc coating commonly refers to adding thicker layers by methods such as hot dip galvanization or other highly advanced techniques. These techniques also lead to a sturdy, longer, longer-lasting finish that provides excellent rust and wear protection even in harsh surroundings.

Technical Parameters:

• Coating Thickness: While zinc-plated rotors often have coatings between 5 and 15 micrometers, zinc-coated rotors may exceed 50 micrometers.
• Corrosion Resistance: Zinc-coated rotors can last up to years, resisting rust or corrosion in severe conditions, while zinc-plated ones deteriorate within a year or two.
• Adhesion Strength: The zinc coating on coated rotors has a better adhesiveness, remaining intact even under high levels of stress.

In conclusion, my preference for either zinc-plated or zinc-coated rotors depends on their intended purpose; for instance, if I were looking for durability and maintenance over time, then I would recommend going with the latter, especially given harsh weather conditions.

Zinc-Coated Rotors vs. Cast Iron: Which is Better?

Considering whether to embrace cast iron vs. going for zinc-coated rotors reveals that both materials have distinctive strengths suited to specific applications. Per my findings from various credible sources, cast iron rotors are characterized by good thermal stability and enhanced wear resistance; hence, they are preferred in heavy-duty applications more than any other type. Nonetheless, they usually corrode if not correctly handled. On the other hand, there is an increased level of corrosion resistance among these types thanks to a thick protective layer, thus making them ideal where moisture and tough conditions are common.

Technical Parameters Justified:

• Thermal Conductivity: Cast iron has superior conduction properties, which are useful during the braking process as they enable efficient heat dissipation.
• Weight: There is an increased weight of cast iron rotors by which they contribute to stability, while this may also affect the vehicle performance. Conversely, the zinc-plated rotors are usually made lighter because of their coating alone, which ultimately enhances car responsiveness.
• Corrosion Resistance: Additionally, my research revealed that zinc-coated rotors outperform cast iron in terms of rust resistance and, therefore, have an extended life span even under harsh conditions.

In conclusion, different application of these types of rotors will determine my choice—cast iron for specific applications like thermal resilience or zinc coated for long lasting and corrosion resistant properties in demanding environments.

Understanding the Durability of Coated Brake Rotors

The durability of coated brake rotors across various reputable sources was investigated, and it was established that coatings’ efficiency has a significant effect on their lifetime and performance. Here are the key technical parameters I identified:

1. Coating Adhesion: The adhesiveness between the rotor and its coat greatly determines its longevity. Strong adhesion helps prevent delamination under high stress, ensuring consistent performance over time.
2. Thickness of Coating: A greater thickness is necessary for better corrosion and wear protection. Some websites say that a coating at least 0.5 mm thick is best for a longer lifespan with no loss in functionality.
3. Temperature Resistance: When brakes are applied heavily, good coatings should not degrade even if exposed to extreme temperatures. Several sources emphasize that such coats must remain intact above 600°F so that they do not fail during severe braking exercises.
4. Abrasion Resistance: Wear must not spoil coated rotors when brake pads touch them. The finest coatings show excellent abrasion resistance, thereby lengthening the rotor’s life and the life of the brake pad.
5. Environmental Resistance: Moisture, salt, and debris are some environmental conditions that affect coated rotors. Independent tests clearly reveal outstanding behavior within these domains by top-rated products available today.

This comprehensive understanding of durability parameters helps me to choose the right rotor type based on specific needs, balancing factors such as performance, longevity, and environmental impact.

Conclusion

Zinc-coated rotors are a good solution for those looking for durability and performance in difficult driving conditions. Zinc’s special properties enable it to be used in these brake rotors with excellent corrosion resistance; they can also act as a barrier against the elements, specifically when concerned about moisture or road salts. You can use zinc-coated rotors to increase the life of your brakes, reduce maintenance costs, and enjoy consistent braking ability. Besides being compatible with several types of brake pad materials, they are suitable for daily drivers and even some high-performance cars. Ultimately, their enhanced ability to withstand abrasion while retaining temperature stability and environmental resistance makes them the leading choice among all other options in the market.

The braking system on your car is the most important part of making sure you’re safe while driving. It keeps you from hitting a cat as it gingerly walks (because it doesn’t care) across the street, allows you to make turn nine on a road course, exit the dragstrip before running into the catch net, or stop as that Prius pulls out in front of you. We were looking for a quick upgrade over the stock iron stoppers, so we turned to Baer Brakes for a replacement set of their EradiSpeed rotors.

The S550 Mustang brakes from the factory work pretty damn well – like supercar good. Our EcoBoost test mule came equipped with Ford’s Performance Pack option. That means that the stock GT four-piston calipers with 13.9-inch rotors in the front and 13.0-inch rotors with single-piston calipers are standard. The EcoBoost/MT-82 manual-equipped S550 is among the lightest Mustang variants in the Ford fleet, and it showed in the results. On the second run, the Mustang stopped in a neck-snapping 104 feet from 60 mph…according to the built-in braking test in the Performance Calculator function. The rest of the results looked like this:

Test One: 2.8 seconds, 106 feet, 1.10G

Test Two: 2.7 seconds, 104 feet, 1.09G

Test Three: 2.9 seconds, 110, 1.09G

All three brake tests were made back to back. As you can see, when the braking system is cold, it stops the slowest out of the three tests, but by the third test, the braking performance is already starting to wane. Could Baer’s EradiSpeed replacement drilled and slotted rotors make a difference? Only time would tell.

As you can tell by the above part numbers, the front EradiSpeed rotors are a tenth of an inch larger than the stock brakes, which won’t affect anything. These two-piece rotors are slotted, cross-drilled, zinc-coated, and direction vaned for optimal cooling and heat dissipation. Depending on the application, the aluminum hats come in billet or forged with stainless steel hardware. Baer even offers a +1 larger rotor option for some vehicles that include new caliper brackets to properly space the caliper off the rotor.

“We basically build a new, unique casting to the Mustang that features a directional vane structure (compared to the OEM pillar type design),” said Rick Elam of Baer. “For the 2015 (depending on application), these will be 48 to 72 directional vanes. Directional vanes are longer (so they add more stability to the rotor), but also, by being curved, they act like a centrifugal pump and draw air to the center (eye) of the rotor and pump it out the edges. The brake system is a heat sink, so the better the rotor’s pumping/cooling efficiency, the better the brake will be, and the longer it will last.”

Baer’s instructions include a pretty extensive process of ‘braking’ in the new rotors. Drive on them for a week, make a bunch of stops from different speeds with different amounts of brake pressure, drive it some more, and do some more braking.

We have to admit; we were a bit apprehensive that the Baer’s were going to improve over the stock brakes. If the Performance Calculator was right, we were either stopping on a section of road made out of mousetrap glue or the EcoBoost Performance Pack Mustang is one of the best stopping vehicles on the road, period. LaFerrari, WHAT?

Once the rotors were broken in we ran our test again on the same stretch of road anad the results came in as:

Test One: 2.9 seconds, 112 feet, 1.09G

Test Two: 2.6 seconds, 94 feet, 1.14G

Test Three: 2.7 seconds, 102 feet, 1.13G

Test Four: 2.8 seconds, 102 feet, 1.11G

All in all, the Baer EradiSpeed rotors reduced our stopping distance by 10 feet, which is huge for a direct rotor replacement. We also noticed that once the brakes were hot, they were less susceptible to fading due to the increased cooling capacity of the drilled and slotted rotors. Not to mention, our Mustang looks a heck of a lot nicer underneath those five-spoke wheels.
