REMOVAL & INSTALLATION
See Figures 1 through 11
- Raise and safely support the vehicle. Remove the rear wheels. Remove the brake drum.
- Remove the shoe anchor springs and unhook the cable eye from the anchor pin. Remove the anchor pin plate.
- Remove the shoe hold-down springs, shoes adjusting screw, pivot nut, socket and automatic adjustment parts.
- Remove the parking brake link, spring and retainer. Disconnect the parking brake cable from the parking brake lever.
- After removing the rear brake secondary shoe, disassemble the parking brake lever from the shoe by removing the retaining clip and spring washer.
- Before installing the rear brake shoes, assemble the parking brake lever to the secondary shoe and secure it with the spring washer and retaining clip.
- Apply a light coating of caliper slide grease at the points where the brake shoes contact the backing plate. Be careful not to get any lubricant on the brake linings.
- Position the brake shoes on the backing plate. The primary shoe (with the short lining) faces the front of the vehicle; the secondary, to the rear. Secure the assembly with the hold-down springs. Install the parking brake link, spring and retainer. Back off the parking brake adjustment, then connect the parking brake cable to the parking brake lever.
- Install the anchor pin plate on the anchor pin. Place the cable eye over the anchor pin with the crimped side toward the drum. Install the primary shoe to the anchor pin.
- Install the cable guide on the secondary shoe web with the flanged hole fitted into the hole in the secondary shoe web. Thread the cable around the cable guide groove.
The cable must be positioned in the groove and not between the guide and the shoe web.
- Install the secondary shoe anchor spring. Make sure the cable eye is not cocked or binding on the anchor pin when installed. All parts should be flat on the anchor pin.
- Apply a thin coat of lubricant to the threads and the socket end of the adjusting screw. Turn the adjusting screw into the pivot nut to the limit of the threads, then back it off one-half turn.
Make sure the socket end of the adjusting screw, stamped with R or L, is correctly installed to the right or left side of the vehicle. The adjusting screw assemblies must be installed on the correct side for proper brake adjustment.
- Place the adjusting socket on the screw and install the assembly between the shoe ends with the adjusting screw toothed wheel nearest the secondary shoe.
- Place the cable hook into the hole in the adjusting lever. The adjusting levers are stamped with R or L to indicate correct installation.
- Position the hooked end of the adjuster spring completely into the large hole in the primary shoe web. Connect the loop end of the spring to the adjuster lever hole.
- Pull the adjuster lever, cable and automatic adjuster spring down and toward the rear, engaging the pivot hook in the large hole of the secondary shoe web.
- Make sure the upper ends of the brake shoes are seated against the anchor pin and the shoes are centered on the backing plate.
- Adjust the brakes, using brake adjustment gauge D18L-1103-A or equivalent.
- Install the brake drum, install the wheel and lower the vehicle.
- Apply the brakes several times while backing the vehicle. After each stop, the vehicle must be moved forward.
