The aim is to bring the pads to full race temperatures, but slowly (too quick bedding results in glazing). This is done by a series of laps where full speeds may be attained but lighter braking pressures are used (i.e. the driver applies the brakes earlier). It is important that the pads are allowed to cool after the bedding process before racing. Ideally the pads will arrive at temperatures in excess of 500°C during the bedding. Pads smoking during the cool-down is not a cause for concern. Specifically for DS1.11, DS3.12 and DSUNO temperatures should arrive at between 500°C and 700°C (as an indication: green and orange thermal paints applied to discs to turn white completely).
Perform at least 15 trial brake applications, initially with reduced pressures (50% of the normal that might be used for that same brake application were it to occur under race conditions) building up to full decelerations after the 15 applications. To shorten the procedure applications can be made along the straights as well as at corners.
On completion of the trial applications, return to the pit lane. Inspect the surface of the brake pads from the two wheels that have been working the hardest. There should be evidence of contact over the full pad area, but without glazing. The pads are now ready to race. Whilst it is recommended that pads are inspected after bedding, if time does not allow this and paragraph 1 has been carried out appropriately, so long as a short period of time has elapsed to allow the brake system to cool (ideally to below 100°C - this might take in excess of five minutes), the pads will be ready to race.
B Suffix Pad Range
Please note that when fitting the DS1.11, DS3.12 or DSUNO materials with the suffix B in their part numbers ,such as WB, GB or ZB ,these pads have received a very high temperature heat treatment during manufacturing.
- This results in a much reduced bedding-in process. These pads allow the number of brake applications mentioned above to be reduced to a simple mechanical mating process of possibly five applications
- The backplates required to undergo this process are also more robust and are lacking the mechanical attachment holes and thus the brake pad is stiffened and less prone to distortion.
- The resins present in the formulation are completely stabilized and therefore are not prone to further reaction in the early stages of the pad life. This eliminates pad material shrinkage.
All Ferodo brake pads citing race or racing on their packaging are solely developed for motorsport use. They are intended for race use only. They have not been developed for use on public roads and must not, under any circumstances, be used on public roads. The nature of racing prevents Federal Mogul from warranting or guaranteeing any aspect of the behavior or performance of the brake pads, specifically because motorsport is inherently dangerous and the use of Ferodo racing brake pads in motorsport results in inherent strains and uses over which Federal-Mogul has no control.
Federal-Mogul warrants only that the Ferodo racing brake pads have been manufactured in accordance with the manufacturing specifications and design for such pads.
In particular, and without in any way limiting the scope of the foregoing disclaimer, no warranty or guarantee, express or implied, is made as to the ability of the Federal-Mogul racing brake pads to protect the user from injury or death. By the usage of such racing brake pads the user explicitly assumes all said risks.
FURTHER TO THE FOREGOING, EXCEPT FOR THE EXPRESS WARRANTY GIVEN IN THE RESPECT OF CONFORMITY OF THE RACING BRAKE PADS TO THE MANUFACTURING SPECIFICATIONS, FEDERAL-MOGUL DISCLAIMS ANY AND ALL WARRANTIES Of ANY KIND, INCLUDING WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
