Brake Pad and Rotor Burnishing
Caution: Refer to Road Test Caution .
Burnishing the brake pads and brake rotors is necessary in order to ensure that the braking surfaces are properly prepared after service has been
performed on the disc brake system.
This procedure should be performed whenever the disc brake rotors have been refinished or replaced, and/or whenever the disc brake pads have been
replaced.
1. Select a smooth road with little or no traffic.
2. Accelerate the vehicle to 48 km/h (30 mph).
Important: Use care to avoid overheating the brakes while performing this step.
3. Using moderate to firm pressure, apply the brakes to bring the vehicle to a stop. Do not allow the brakes to lock.
4. Repeat steps 2 and 3 until approximately 20 stops have been completed. Allow sufficient cooling periods between stops in order to properly
burnish the brake pads and rotors.
