Brake Drums


Removal & Installation

See Figures 1 and 2

Brake 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 any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

  1. Raise and support the rear end on jackstands. Block the front wheels
  3. Remove the wheel, then the drum from the vehicle. On some models you may have to remove spring nuts securing the drums to the wheel studs before removing the drum.

It may be necessary to back off the brake adjusters to remove the drum.

  1. When placing the drum on the hub, make sure that the contacting surfaces are clean and flat.

Using an inside micrometer, check all drums. Should a brake drum be scored or rough, it may be reconditioned by grinding or turning on a lathe. Do not remove more than 0.030 in. (0.76mm) thickness of metal. If a drum is reconditioned in this manner, it is recommended that either the correct factory supplied 0.030 in. (0.76mm) oversize lining be installed, or a shim equal in thickness to the metal removed be placed between the lining and the brake shoe so that the arc of the lining will be the same as that of the drum.
