See Figure 1
- Raise and support the rear of the vehicle on jackstands.
- Remove the rubber cover from the backing plate.
- Insert a brake adjusting tool through the hole in the brake backing plate. Turn the toothed adjusting nut to spread the brake shoes, making contact with the brake drum.
When adjusting the brake shoes, turn the wheel until considerable drag is felt. If necessary, hit the brake drum with a rubber hammer to align the shoes with the drum.
- When considerable drag is felt, back off the adjusting nut a few notches, so that the correct clearance is maintained between the brake drum and the brake shoes. Make sure that the wheel rotates freely.
BRAKE PEDAL HEIGHT ADJUSTMENT
See Figure 2
Before adjusting the pedal, make sure that the wheel brakes are correctly adjusted. Pedal free height adjustment can then be made using the brake booster input rod.
- Loosen the lock nut on the brake booster input rod.
Adjust the pedal height by rotating the input rod, until the proper pedal height is obtained. The pedal height (floorboard to pedal pad) should be as follows:
1982-86 vehicles-MTX-7.64-8.03 in. (194-204mm)
- Once the proper height measurement has been obtained, tighten the locknut and verify proper brake light operation.
