Proper bedding starts with new pads being run through one complete heat cycle and then cooled before using them in race conditions. Best performance and overall results will come from bedding new pads on an already bedded or “seasoned” rotor. Used rotors must be flat and smooth. New pads can be effectively bedded to new rotors, if some care is taken at first break-in.
To bed-in your brake pads, begin by applying the brakes at low speeds to assure proper system operation. On the race track or other safe location, make a series of hard stops from moderate to slower speeds. Gradually increase the speed and the braking until the pads reach a hot racing temperature. If any brake pad fade is experienced during the bed-in, immediately begin the cool down process. Drive the car at slow to moderate speeds while the pads begin to cool, and be sure not to drag the brake pedal. Pit the car with minimal brake use and allow the brakes to finish cooling before subjecting them to race conditions. This procedure will minimize friction values over the broadest possible temperature band.
