For vehicles equipped with rear drum brakes, the rear drum brake shoes serve as the parking brakes. Refer to the procedures under Rear Drum Brakes.
- Raise and support the rear of the vehicle safely on jackstands.
- Remove the rubber plug, if equipped, from the rear of the backing plate. The brake shoe adjuster wheel is accessed beneath this plug.
Insert a suitable brake adjustment tool into the backing plate slots and engage the lowest possible tooth on the star wheel. Move the end of the brake tool downward to move the star wheel upward and expand the adjusting screw. Repeat this operation until the brake shoes contact the rotor surface, then back off the adjuster 2 to 3 turns.
NOTEThe brake drag should be equal at both wheels.
- After the brakes are adjusted, install a rubber cover into each of the backing plate slots.
Remove the jackstands, and lower the vehicle.
NOTEPump the brake pedal to seat the brake shoes before moving the vehicle.
- Remove the adjusting hole cover from back plate.
- Turn adjusting screw using a slot-type screwdriver until brake shoe is in close contact with the drum.
- Turn back (downward) the adjusting screw 3 or 4 notches.
- Install the adjusting hole cover to back plate.
