An inspection hole is provided in the backing plate of each rear wheel which allows the brakes to be checked without removing the drum. Remove the hole plug, then check the lining thickness through the hole. If below minimum, the shoes must be replaced. Always install the plug after inspection making certain it is properly seated and tight.
This method doesn't provide a lot of information about how the brakes are wearing since it only shows one part of one shoe, but is a quick and easy first check. The only way to see the friction faces of the shoes is to remove the brake drums. No generalities can be drawn between the left and right side shoes, so both drums must be removed to perform a proper inspection.
With the drums removed:
- Liberally spray the entire brake assembly with aerosol brake cleaner. Do not use other solvents, compressed air or a dry brush.
- Measure the thickness of the friction surface on each shoe at several different locations. If any measurement is below the minimum thickness, replace all the shoes (both sides) as a set.
- Check the contact surfaces closely for any signs of scoring, cracking, uneven or tapered wear, discoloration or separation from the backing plate. Anything that looks abnormal should be replaced.
- If the shoes are in otherwise good condition except for glazing (a shiny, hard surface), the glaze may be removed by light sanding with emery cloth. Also, lightly sand the inside of the drum to de-glaze its surface. Do not attempt to rub out grooves or ridges; this is best done with a resurfacing lathe. After sanding the components, wash them thoroughly with aerosol brake cleaner to remove any grit.
REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5, 6 and 7
Although this procedure can be accomplished with common hand tools, there are a variety of specialty brake tools available in retail stores which make the job much easier.
- If equipped with an air bag, disconnect the negative battery cable and properly disable the Supplemental Restraint System (SRS), as detailed in Chassis Electrical .
- Remove the rear wheel and brake drum.
- Saturate the rear brake assembly with brake cleaning fluid.
- On 1990 and later Accords, remove the upper return spring from the brake shoe.
All springs and fittings should be labeled or diagrammed at the time of removal. The amount of time saved during reassembly makes the extra effort well worthwhile.
- Remove the tension pins by pushing the retainer spring and turning them.
- Slightly lower the brake shoe assembly and remove the lower return spring.
- Remove the brake shoe assembly.
- Disconnect the parking brake cable from the lever.
- Remove the upper return spring, self-adjuster lever and self-adjuster spring. Separate the brake shoes.
- Remove the wave washer, parking brake lever and pivot pin from the brake shoe by removing the C-clip.
- Install the parking brake lever and wave washer on the pivot pin and secure with a new C-clip.
Pinch the C-clip securely to prevent the pivot pin from coming out of the brake shoe.
- Connect the parking brake cable to the parking brake lever.
- Apply grease on each sliding surface of the brake backing plate.
Do not allow grease to come in contact with the brake linings. Grease will contaminate the linings and reduce stopping ability.
- Clean the threaded portions of the clevises of the adjuster bolt. Coat the threads with grease. Turn the adjuster bolt to shorten the clevises.
- Hook the adjuster spring to the adjuster lever first, then to the brake shoe.
- Install the adjuster bolt/clevis assembly and the upper return spring.
- Install the brake shoes to the backing plate.
- Install the lower return spring, the tension pins and retaining springs.
- On 1990 and later Accords, connect the upper return spring.
- Turn the adjuster bolt to force the brake shoes out until the brake drum will not easily go on. Back off the adjuster bolt just enough that the brake drum will go on and turn easily.
- Install the wheel; lower the vehicle to the ground.
- If equipped, enable the SRS system and connect the negative battery cable.
- Depress the brake pedal several times to set the self-adjusting mechanism. Adjust the parking brake.
