    Warning: Refer to Brake Dust Warning in the Preface section.

    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.

    Note: Burnishing the brake pads and brake discs is necessary whenever the brake discs have been refinished or replaced, and/or whenever the brake pads have been replaced to make sure that the braking surfaces are correctly prepared.

  1. Select a smooth road with little or no traffic.
  2. Accelerate the vehicle to 70 km/h (43 mph).
  3. 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.

    Note: DO NOT allow the brakes to lock.

  4. Using moderate pressure, apply the brakes to bring the vehicle to a stop.
  5. Repeat steps 2 and 3 until approximately 20 stops have been completed. Allow sufficient cooling periods of no less than 500 meters between stops in order to correctly burnish the brake pads and brake discs.
