REMOVAL & INSTALLATION
See Figures 1 through 22
The parking brakes on rear disc brake equipped models are actually small drum brakes which work inside the brake rotor/hub. Their design and construction is virtually identical to the rear drum service brakes found on other models. Also, replacement shoes/linings are usually bought on an exchange basis, as are most drum type service brake shoes.
- Remove the rear disc brake assembly. Hang the caliper from the coil spring with a piece of string so the hose is not stretched.
- Using pliers, remove the brake return springs. Remove the shoe strut with the springs.
- Slide out the front brake shoe and remove the shoe adjusting screw set. Remove the tension spring, and remove the shoe.
- Slide out the rear shoe, and disconnect the parking brake cable from the parking brake shoe lever. Remove the rear brake shoe.
- Measure the brake shoe lining thickness. Standard thickness is 0.079 inch (2mm), and minimum allowable thickness is 0.039 inch (0.99mm). If the lining is thinner than minimum, replace the brake shoes on both wheels (to maintain even braking on both wheels). Maximum disc inside diameter is 6.61 inch (167mm).
- To reassemble the parking brake, apply non-melting type grease to the sliding surfaces on the back plate as shown. Apply the same grease to the adjusting screw threads.
- Compress the cable spring and connect the parking brake lever to the cable.
- Slide the rear brake shoe between the hold-down spring seat and the backing plate.
- Install the tension spring to the rear shoe, and connect the front shoe to the tension spring. Install the shoe adjusting screw set between the front and rear shoes. Slide in the front shoe between the shoe hold-down spring seat and the backing plate.
- Install the front shoe return spring, and also the strut with the spring.
- Install the brake disc assembly by aligning the groove on the rear axle flange with the service hole on the disc. You may have to back off the adjuster to install the hub.
- Temporarily install the disc hub nuts. From the front side of the hub, turn the adjuster star wheel and expand the shoes until the disc cannot be turned by hand. Back off the adjuster wheel about 8 turns.
- Inspect and adjust the parking brake lever travel.
