Removal & Installation
- Raise and support the vehicle safely.
- Remove the wheel.
Remove the push-on nuts, if equipped.
NOTEIt may be necessary to back off the brake shoe adjustment in order to remove the brake drum. This is because the drum might be grooved or worn from being in service for an extended period of time.
- If the brake drum will not slide off the hub easily, remove the brake adjusting hole cover from the backing plate. Insert a screwdriver and a Brake Adjustment Tool (D81L-1103-C) or equivalent.
- Disengage the brake shoe adjusting lever and loosen the brake adjuster screw.
- Remove the brake drum.
- If the inside of the drum has a coating of rust or a ridge, clean it with a piece of coarse sandpaper before installation.
- Before installing a new brake drum, be sure to remove any protective coating with brake cleaner or a suitable fast-drying cleaner.

- If the drum will not slide off with light force, the brake shoes will need to be backed off. Remove the rubber plug on the backing plate and insert a screwdriver and a brake adjusting tool into the slot. Hold the adjuster lever away from the adjuster wheel with the screwdriver and back of the adjuster wheel with the brake adjusting tool.
- Remove the brake drum. Inspect the drum for wear and/or damage. Machine or replace as necessary. If machining, observe the maximum diameter specification.
