REAR DRUM BRAKES

Brake Shoes

Remove the drum and inspect the lining thickness of both brake shoes. The rear brake shoes should be replaced if the lining is less than 0.039 in. (1mm) thick above the rivet (so that the lining is thicker than the metal shoe backing in most cases) in order to prevent the rivet from scoring the drum. On bonded shoes the same specification should be used and the thickness of the bonded lining should be 0.039 in. (1mm) thick above the metal shoe backing plate. As with all brake service, keep in mind that local regulations take precedence over these specifications. Always check with your local authorities to be sure you are in compliance with local laws.

Inspect the brake shoes for excessive or uneven wear, fluid contamination, bent and/or broken parts and cracks. If any of these conditions exist, replace the brake shoes.

Brake shoes should always be replaced in sets.

Also service one brake assembly at a time. This will allow for visual comparison in the event of difficulty.

1. Raise the vehicle and safely support on jackstands. Remove the wheel and tire assembly.
2. Remove the brake drum.
3. Remove both return springs carefully with a pair of brake pliers or equivalent.
4. Remove both retaining clips by first turning them 90 degrees with a pair of pliers to line up the slot in the lip with the flat end of the pin, then pull them off the pins.
5. Disconnect the brake shoes from the adjuster side first, then the wheel cylinder side, and pull them off the backing plate.
6. If equipped with rear drum parking brakes, unfasten the parking brake cable from the parking lever on the rearward brake shoe.
7. Inspect all the brake shoe installation hardware and replace any piece(s) which are worn or damaged.

To install:

8. Apply brake grease to the backing plate where the brake shoes contact it.
9. Install the brake shoes to the wheel cylinder, then to the adjuster. Secure in place with the two retaining clips.

10. Assemble the return springs. The upper spring is thinner.
11. Adjust the brake shoe diameter to 7 in. (180mm). Measure the diameter in at least 3 places around the shoes.
12. Install the drum and adjust the brake shoes.
13. Install the wheel and tire assembly on the vehicle, and lower.
