If the discs were previously being used with PFC brake pads then the bedding-in procedure will be achieved quickly with new PFC pads. Discs previously bedded using a different manufacturer’s pads require a slightly longer process. With brake cooling ducts open and fully functional, perform the following procedures.
All PFC RaceReady® brake pads are pre-treated to be race and street ready. This treatment is done in the final step of the manufacturing process when the surface of the friction material is brought up to temperature in order to simulate a bedding cycle. However, proper bedding is still required using your rotors with the new CarbonMetallic® pads. The following process below is suggested in order to achieve the best performance, consistency and durability of the brake pad.
STEP 1 On the first lap, perform several stops with progressively higher pedal pressure and braking force and from higher speeds. You will feel the effectiveness of the brakes increase with each successive brake application.
STEP 2 This should take six to ten snubs per lap and is usually completed in one or two laps. If non-PFC friction materials were previously run on the discs then this procedure could take as many as three to five laps.
STEP 3 Running additional laps is the best way to accomplish the new transfer layer and, due to the higher surface temperatures, will assure a complete removal of the old friction materials from the disc.
STEP 4 The disc should be allowed to cool as much as is practical, with ambient temperature being ideal. Allowing the disc to cool to ambient temperature will increase disc life and performance.
STEP 5 The pads are now properly bedded to provide consistent performance. The pads should be brought back up to the operating temperature range to guarantee optimum braking power. This depends upon the specific compound.
Note: Sanding or machine grinding the discs will not decrease the bed-in time. Whenever new PFC brake pads are installed, the time spent taking disc temperatures, tyre temperatures and pressures and a debriefing with the driver is usually a sufficient cool down period.
