Chevrolet Sonic Repair Manual: Brake Pad and Rotor Burnishing
Warning:
Road test a vehicle under safe conditions and while obeying all traffic laws. Do not attempt any maneuvers that could jeopardize vehicle control. Failure to adhere to these precautions could lead to serious personal injury and vehicle damage.
Burnishing the brake pads and brake rotors is necessary in order to ensure that the braking surface 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 brake pads have been replaced.
- Select a smooth road with little or no traffic.
- Accelerate the vehicle to 48 km/h (30 mph).
- Using moderate pressure, apply the brakes to bring the vehicle to a stop. Do not allow the brakes to lock.
- 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.
Note:
Use care to avoid overheating the brakes while performing this step as it may adversely affect the heating characteristics of the NEW brake pad material.
