REMOVAL & INSTALLATION
See Figures 1 and 2
We recommend replacement of the brake drums in axle sets for added safety and reliability
- Remove the hub cap (if used) and loosen the lug nuts. Release the parking brake.
- Block the front wheels, raise the rear of the car, and support it with jackstands.
- Remove the lug nuts and the wheel.
- Remove the brake drum retaining screws, if equipped.
- Remove the brake drum. Tap the drum lightly with a rubber mallet in order to free it. If the drum cannot be removed easily, insert a tool into the backing plate hole and hold the automatic adjusting lever away from the adjusting bolt. Using another tool relieve the brake shoe tension by turning the adjusting bolt clockwise. If the drum still will not come off, use a puller; but first make sure that the parking brake is released.
Don't depress the brake pedal once the drum has been removed
- Inspect the brake drum.
- Brake drum installation is performed in the reverse order of removal.
- Clean the drum.
- Inspect the drum for scoring, cracks, grooves and out-of-roundness. Replace or turn the drum, as required.
- Light scoring may be removed by dressing the drum with fine emery cloth.
- Heavy scoring will require the use of a brake drum lathe (refer to a local machine shop) to turn the drum.
