Brake 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 any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.
Jack the vehicle up and support it so that the wheels to be worked on are off the ground.
Turn the adjustment starwheel so that the brake shoes are retracted from the brake drum.
Remove the wheels and the hubs and rums to give access to the brake shoes.
Install wheel cylinder clamps to retain the wheel cylinder pistons in place and prevent leakage of brake fluid while replacing the shoes.
Remove the return springs with a brake spring remover tool.
On models with self-adjusters, remove the adjuster cable, cable guide, adjuster lever and adjuster springs.
Remove the hold-down washers and springs and remove the brake shoes.
Before installing the new shoes, now would be a good time to inspect the oil seals in the hubs. If the condition of the seals is doubtful, replace them. Also check the wheel cylinders for leakage. Pull back the dust covers. If there is fluid present behind the dust cover, the wheel cylinder must be rebuilt or replaced.
Clean the backing plate with a brush or cloth. Place a dab of Lubriplate® on each spot where the brake shoes rub on the backing plate.
Always replace brake linings in axle sets. Never replace linings on one side or just on one wheel.
Install the brakes in the reverse order of removal. When the brake parts have been installed in their correct positions, adjust the adjusting screw assemblies to a point where approximately
in. of threads are exposed between the starwheel and the starwheel nut.
