Removal & Installation
- Before servicing the vehicle, refer to the Precautions section.
Remove or disconnect the following:
Rear wheels and brake drums
Rotate the automatic adjuster starwheel enough so both shoes move out far enough to be free of the wheel cylinder boots.
Parking brake cable from the actuating lever. Disconnect parking brake cable one side at a time.
- Thoroughly clean and dry the backing plate. To prepare the backing plate, lubricate the bosses, anchor pin and parking brake actuating lever pivot surface lightly with lithium based grease.
- Remove, clean and dry all parts still on the old shoes. Lubricate the starwheel shaft threads with anti-seize lubricant.
- Assemble both brake shoes, the top shoe to shoe return spring, automatic adjuster and automatic adjuster lever before mounting on vehicle. Make sure the ends of the automatic adjusters are positioned above the extruded pins in the webbing of the brake shoes prior to installation.
Install or connect the following:
Brake shoe assembly onto the brake support plate and secure with the hold-down springs
Rotate the serrated adjuster nut to remove the free-play from the adjuster assembly.
Automatic adjuster lever spring on the lead brake shoe assembly and the automatic adjuster lever
Adjust brake shoes so not to interfere with brake drum installation. Install the rear brake drum.
NOTEAfter installing the brake drums, pump the brake pedal several times to partially adjust the brake shoes. To verify proper operation of the self-adjusting parking brake, be sure that both rear brakes are not dragging when the parking brake pedal is released.
Rear wheels and lug nuts. Torque the lug nuts, in a star pattern sequence, to 100 ft. lbs. (135 Nm).
- Road test the vehicle. The automatic adjusters will continue brake adjustment during the road test of the vehicle.
