Drum Installed

WARNING: Do not inhale dust from brakes or associated components.Inhalation of dust can be injurious to your health.Compressed air or brushes must not be used to clean brakes, brake drums and associated components. A vacuum cleaner equipped for this purpose should be carefully used to remove any dust (rotunda model 091-00001).Adherent dust should be removed with a damp rag.Any dust should be contained in a sealed and labeled bag for disposal.Wear an approved high efficiency cartridge or air line respirator and use extra caution to avoid breathing this dust.Always use non-asbestos replacement parts.

NOTE: The rear brakes are automatically adjusted while driving the vehicle in reverse and sharply applying the brakes, and then driving forward. It may be necessary to do this several times to obtain the proper rear brake adjustment. Manual brake adjustment is required only after the brake shoes have been replaced, or if brake shoe adjusting lever kit (2A176) has malfunctioned and has been repaired or replaced. Perform the manual adjustment with the brake drums (1126) removed, using Brake Adjustment Gauge D81L-1103-A or equivalent and the procedure described below. When adjusting the rear brake shoes, check the parking brake rear cable and conduit (2A635) for proper adjustment. Make sure the equalizer operates freely.

Adjust the single anchor brake by turning the adjusting screw (part of brake shoe adjusting screw nut (2047)) located between the lower ends of the shoes.

1. Place transmission (7003) in neutral. Raise the vehicle until the tires clear the floor. Install safety stands.

Drum Brake Adjuster:

2. Remove the cover from the adjusting hole at the bottom of the brake backing plate, and turn the adjusting screw (part of brake shoe adjusting screw nut) using Brake Adjusting Tool D81L-1103-C or equivalent inside the hole to expand the brake shoes until they drag against the brake drum and lock the brake drum.
3. When the shoes are against the brake drum, loosen the adjusting screw (part of brake shoe adjusting screw nut) an additional 10 to 12 notches so that the brake drum rotates freely without drag.
4. If the brake drum does not rotate freely, remove the wheel and brake drum, and vacuum out any dust and dirt from the linings using Rotunda Brake and Clutch Service Vacuum 091-00001 or equivalent.
5. Using sandpaper, remove any rust from the points where the shoes touch the brake backing plate.
6. Check brake backing plate for damage. If none is found, apply a light coating of Disc Brake Caliper Slide Grease D7AZ-19590-A (ESA-M1C172-A) or equivalent. Do not get the lubricant on the lining.
7. Install the wheel and brake drum and adjust the shoes.
8. Install the adjusting hole cover on the brake backing plate.
9. Check and adjust the other rear brake assembly.
10. Apply the brakes. If the pedal travels more than halfway to the floor, there is too much clearance between the brake shoes and the brake drums. Repeat Steps 2 and 3 of this procedure.

CAUTION: Perform the road test only when the brakes will apply and the vehicle can be safely stopped.

11. When the rear brake shoes have been properly adjusted, lower the vehicle and road test to check brake operation.
