Brake Shoes

INSPECTION

CAUTION
Brake pads and shoes 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.

1. Remove the brake drum.
2. Measure the wear of the brake lining at the place worn the most. The service limit for replacement is 0.039 in. (1.0mm).

   Fig. 1: Measure the thickness of the lining where it is worn the most

   NOTE: When servicing drum brakes, only dissemble and assemble one side at a time, leaving the remaining side intact for reference.

3. Replace the shoe and lining assembly is any located is less than the limit. Whenever the shoe and lining assembly is replaced, be sure to replace the left and right side assemblies as a set to prevent the car from pulling to one side when braking.
4. If there is a big difference between the thicknesses of the shoe and lining assembly on the left and right sides, check the sliding condition of the wheel cylinder piston.
