INSPECTION



After removing the brake drum, wipe out the accumulated dust with a damp cloth.


CAUTION
DO NOT blow the brake dust out of the drums with compressed air or lung power. Brake linings contain asbestos, a known cancer causing substance. Dispose of the cloth after use.

Inspect the drum for cracks, deep grooves, roughness, scoring or out-of-roundness. Replace any brake drum which is cracked.

Smooth any slight scores by polishing the friction surface with the fine emery cloth. Heavy or extensive scoring will cause excessive brake lining wear and should be removed from the brake drum through resurfacing.
