REMOVAL & INSTALLATION
See Figures 1 through 18
An inexpensive brake spring removal tool, available at most auto parts stores, will make this procedure much easier.
- Jack the vehicle up and safely support it so that the wheels to be worked on are off the ground.
- Turn the adjuster screw's star wheel, so that the brake shoes are retracted from the brake drum.
- Remove the wheels and brake drums 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.
- Remove the adjuster cable, cable guide, adjuster lever and adjuster springs.
- Remove the hold-down washers and springs, then remove the brake shoes.
- 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 the linings on one side or on only one wheel.
- Thoroughly clean the backing plate.
- Apply a thin coat of multi-purpose chassis lube to the mounting pads on the backing plate.
- Transfer the parking brake actuating lever to the new secondary shoe.
- Position the brake shoes on the backing plate and install the hold-down springs. Don't forget to engage the parking brake lever with the cable.
- Install the parking brake actuating bar and spring between the parking brake lever and primary shoe.
- Install the self-adjusting cable, cable guide and upper return springs.
- Thoroughly clean the adjuster screw assembly and lightly lubricate the threads with lithium based grease.
- Install the adjuster screw assembly.
- Install the self-adjusting cam and lower spring. A big pair of locking pliers is good for this job.
- Check the surface of the brake shoes for any grease that may have gotten on them.
- Install the drum and reach through the adjusting opening in the back plate with a brake adjusting tool. Turn the star wheel outward so that the brakes lock the drum, then, holding the adjusting cam with a thin screwdriver, turn the star wheel back so that the drum is free and no drag is felt.
- Once the wheels are on and the vehicle is down, Back it up several times, applying the brakes to actuate the self-adjusters.
