Brake Burnishing (new vehicle)

s2 dm 13.08.000

Important: Check the brake system and ensure that it is in proper operating condition before attempting the brake burnishing procedure.

  1. In a safe area, make 10 sharp brake applications or "snubs," slowing the vehicle from 40 to 20 mph (64 to 32 km/h) using light (approximately 10 to 20 psi [69 to 138 kPa]) brake pressure.
  2. Make 10 stops from 20 mph (32 km/h) using moderate (20 to 30 psi [138 to 207 kPa]) brake pressure.
  3. Make 2 stops from 20 mph (32 km/h) using hard (full application of air pressure) brake applications.

    4. Note: After the hard brake applications, it is normal to notice a hot brake odor.

  4. Drive the vehicle 5 to 7 miles (8 to 11 km) allowing the brakes to cool, and then come to a stop.

    5. Note: After performing the burnishing procedure, there should be no brake noise and the brakes should have good stopping ability.

  5. If the brakes pull the vehicle to one side or grab after the burnishing procedure, contact a Freightliner dealer for assistance.
