Brake Rotor/Disc: Removal and Replacement
Brake Pad and Rotor Burnishing
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.

Removal Procedure
Notice: Any new rotor must have the protective coating removed from the friction surfaces before being placed in service. Remove the protective
coating using denatured alcohol or an equivalent brake cleaner, and wipe the surface clean with clean cloths. Do not use gasoline, kerosene, or other
oil base solvents which may leave an oily residue. This residue is damaging to the brake lining and is flammable.
1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the fluid level is midway between the maximum-full point, and the minimum allowable level, no fluid needs to be removed from the reservoir
before proceeding.
3. If the fluid level is higher than midway between the maximum-full point, and the minimum allowable level, remove fluid to the midway point
before proceeding.
4. Remove the tire and wheel assembly.
5. Mark the relationship of the rotor to the hub.
