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.
REMOVAL & INSTALLATION
See Figure 1
- Block the front wheels of the vehicle.
- Raise and support the rear of the vehicle on jackstands.
- Remove the wheel and drum.
- Remove the rear brake shoe assemblies.
- Disconnect the brake line at the fitting on the brake backing plate. It is a good idea to use a flare nut wrench to keep the flare nut from "rounding out" when being loosened.
- Remove the screws that hold the wheel cylinder to the backing plate, then pull the cylinder off of the brake shoe backing plate.
- Clean the backing plate with brake parts cleaner.
- Position the new rear brake wheel cylinder onto the brake backing plate.
- Install the wheel cylinder retaining nuts onto the wheel cylinder studs until snug.
- Install the rear brake shoe assemblies, as described earlier in this section.
- Install the rear drums and wheels.
- Bleed the brake system.
- Lower the rear of the vehicle, then remove the front wheel blocks.
