Brake Disc (Rotor)


Brake pads and shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from brake surfaces! When cleaning brakes, use commercially available brake cleaning fluids.


See Figures 1 and 2

  1. Raise the vehicle and support safely. Remove appropriate wheel assembly.
  3. Remove the caliper and brake pads. Support the caliper out of the way using wire.
  5. The rotor on most models is held to the hub by 2 small threaded screws. Remove screws, if equipped, and pull off the rotor.

Using a micrometer, measure the disc thickness in at least eight positions, approximately 45 degrees apart and 0.39 in. (10mm) in from the outer edge of the disc. The minimum thickness is 0.87 in. (22mm), with a maximum thickness variation of 0.0006 in. (0.015mm).

If the disc is below limits for thickness, remove it and install a new one. If the thickness variation exceeds the specifications, replace the disc or turn rotor with on the car type brake lathe.
