DISCLAIMER

Ferodo Racing Brake Pads that are labeled for racing use are specifically designed and manufactured for motorsport applications only. These pads are not suitable for road use and must not be used on public roads under any circumstances. The nature of racing, with its inherent risks, prevents Federal-Mogul from guaranteeing or warranting the performance of these brake pads in real-world conditions. Motorsports place unique stresses on components that Federal-Mogul cannot control, and therefore, no warranty is provided for use on public roads.

Warranty and Limitations: Federal-Mogul guarantees that Ferodo Racing Brake Pads are manufactured according to strict specifications and designed to perform within motorsport conditions. However, no warranty is offered for protection against injury or death resulting from their use. By using these racing brake pads, users assume full responsibility for the risks involved.

In addition to the above, except for the express warranty regarding the conformity of the brake pads to manufacturing specifications, Federal-Mogul disclaims any and all warranties, including implied warranties of merchantability or fitness for a particular purpose.

Testing:

All performance and driving results referenced are based on internal and external performance tests, along with recommendations from experienced test drivers.

FEATURES AND BENEFITS

---

ISO16949 & 14001 Certified Production

All Ferodo Racing brake pads are manufactured to the highest ISO quality standards at Federal Mogul's dedicated manufacturing facility in Italy. With 26 separate quality controls during production, every brake pad is guaranteed to maintain consistent performance and repeatability across all batches.

Precision Engineering

The back-plates of all Ferodo Racing brake pads are made from high-tensile steel, minimizing distortion under the high clamping forces common in motorsport applications. Manufactured with high tolerances, including flatness, parallelism, and overall thickness, these pads ensure a rapid and uniform transmission of pressure from the brake system, enhancing performance and consistency.

Thermal Under-layer

Unlike many competitors, Ferodo Racing brake pads feature a thermal under-layer between the backing plate and friction material. This innovative feature helps to lower brake caliper temperatures by up to 80°C, reducing the risk of brake fluid boiling, which can cause a spongy pedal feel during use.

Disc Friendly

Ferodo Racing brake pads are designed to be gentle on brake discs, optimizing both pad and disc life. Our philosophy is to balance pad durability with minimal disc wear, ensuring the longevity of both components without compromising braking performance.

High Controllability

Ferodo Racing brake pads are engineered to offer a consistent coefficient of friction (µ) across a wide range of temperatures, pressures, and vehicle speeds. This results in a linear brake response, giving drivers a predictable and controlled braking experience.

Wide Range of Material choices and Fitments

With one of the broadest selections of pad shapes in the racing and performance brake market, Ferodo Racing offers a variety of compounds to meet specific needs. Whether you're looking for a solution for track days or high-performance racing, Ferodo Racing brake pads provide the perfect fit for your vehicle and application.

PAD BEDDING

---

Bedding-in Process for Ferodo Racing Brake Pads

The goal of bedding-in is to gradually bring the brake pads to full race temperatures. Rapid heating can cause glazing, which reduces pad effectiveness. Ideally, the pads should be allowed to cool between bedding and racing, but if time doesn’t permit, the pads can be used immediately with a potential reduction in product life of about 10%.

How to Bed In Ferodo Racing Brake Pads

Follow this process for an effective bedding procedure:

1. Initial Application: Perform at least 15 trial brake applications, starting with 50% brake pressure of the normal race conditions. Gradually build up to full deceleration after completing the 15 applications. To save time, apply the brakes on straight sections of the track as well as in corners.
2. Target Temperature: Aim for temperatures above 500°C during the bedding process. During the bedding, it’s important to ensure gradual temperature increase to avoid glazing.
3. Thermal Treatment Pads: Pads with the part numbers that include WB, ZB, GB, TL180, DB, FB have undergone intense thermal treatment during production. For these, reaching 500°C during bedding is not as critical, and the number of applications can be reduced. Bedding for these compounds primarily serves as a mechanical mating between the pad and the disc.
4. Pad Smoking: It is normal for pads to produce smoke during the cool-down phase. For specific compounds like DS1.11, DS3.12, and DSUNO, the temperatures should reach between 500°C and 700°C. You can check this by observing thermal paint on the discs, which should change color completely or partially (from green to orange).


5. Cooling Ducts: To achieve the necessary temperatures, it may be necessary to close the cooling ducts during the bedding phase.
6. Inspection: After completing the trial applications, allow the pads to cool. Inspect the surface of the brake pads on the two wheels that have experienced the most stress. There should be at least 80% contact coverage without any visible glazing.

Ready for Racing

After bedding is complete, if time allows, inspect the pads for any visible issues. Ideally, the brake system should be cooled to below 100°C (which might take more than five minutes). Once the system has cooled, your pads will be ready for racing.

Key Tips:

• Follow the gradual bedding process to ensure the pads bed in properly.
• Allow the brake system to cool between bedding and racing whenever possible.
• Ensure no glazing occurs by inspecting the pads after the bedding process.

Figures for Reference:

• Red Plot: Brake pressure against time.
• Green Plot: Disc temperature against time.

The red plots in Figure 1 show brake pressures during bedding at 50% of race conditions. The temperature build-up during bedding can be seen peaking at the desired levels for optimal pad performance.580°C, which is quite close to the full race temperature.



Figures 3 and 4 below illustrate the appearance of DS3.12 pads that have been properly bedded-in. The pad surface is even, with a dull sheen.


Figure 5 – Example of DS3.12 pad that has not been properly bedded. In this case the final disc temperatures reached were not sufficient and/or insufficient applications were made to allow mechanical mating.  In this case pad surface has a non-uniform appearance and these streaks may have a glassy appearance.
