REMOVAL & INSTALLATION
See Figures 1 through 13
- Raise and safely support the vehicle on jackstands so that all four wheels are off the ground.
- On vehicles equipped with cam adjustment brakes, turn all eccentric cams to the lower side of the cam. On vehicles equipped with star wheel adjustment, turn the star adjuster all the way in.
- Remove the wheels and the hubs and drums to give access to the brake shoes.
- Install wheel cylinder clamps on the wheel cylinder 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 removal tool.
- On models with self-adjusters, remove the adjuster cable, cable guide, adjuster lever and adjuster springs.
- Remove the hold-down clips or 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 molybdenum disulfide grease on each raised pad where the shoes rub the backing plate.
Always replace brake shoes in axle sets. Never replace linings on only one side or just on one wheel.To install:
- Install the parking brake cable and lever on the secondary shoe. Secure the lever with a washer and new U-clip.
- Install the guide and self-adjuster cable on the anchor pin.
- Install the shoes, one at a time, on the backing plate and secure them with the hold-down springs, pins and retainers.
- Install the cross-strut and spring.
- Install the star wheel adjuster, spring and lever.
- Install the return springs.
- Make sure that the brake shoe surfaces are clean and free from any contamination.
- Perform the initial brake shoe adjustment, outlined at the beginning of this section.
- Install the drums and wheels, lower the truck and check brake operation. On Jeep vehicles without self-adjusters, refer to the Adjustment procedures at the beginning of this section. On vehicles with self-adjusters, drive the Jeep in a series of alternating forward and reverse stops. Usually 10-15 full stops in reverse are sufficient.
