This is taken directly from the insert that comes with Hawk Ferro-Carbon Racing Brake Pads. This is not for street pads and this procedure should not be attempted on public roads. It is reproduced as a reference for all us racers that lose things.
All brake pads have to be bedded-in with the rotor they will be used against. Even though Hawk Performance burnishes the pads in the factory, a transfer film must be generated at the pad at rotor interference for optimal performance. Whether it is new or used rotors, you must follow the bed-in steps listed below to maximize brake performance.
Step 1: Seal all brake ducts
Step 2: Slowly engage brakes 6 to 8 times at medium speeds. Do not drag brakes or come to a complete stop.
Step 3: Increase speeds to simulate race conditions; allow 6 to 8 high pressure (500 psi) snubs at racing speeds. Total engagement for step 2 and 3 should be a maximum of 15 to 20.
Step 4: Removed brake duct seals. Allow the system to cool for about 15 minutes. Do not engage brakes while car is parked or during cool down period.
Your Hawk Rotors and Hawk Performance pads are now ready for race! Do not sand or grind the brake pads or rotors after this burnishing procedure has been completed.
