See Figure 1
The rear brakes are automatically adjusted while driving the vehicle. Manual brake adjustment is required only after the rear brake shoes and linings have been replaced, or if the adjuster has malfunctioned and has been repaired or replaced. Perform the manual adjustment with the brake drum removed, using Brake Adjustment Gauge D81L-1103-A or equivalent.
- Raise and safely support the rear end of the vehicle on jackstands.
- Remove the tire and wheel assembly, then remove the brake drum.
- Apply a small quantity of Disc Brake Caliper Slide Grease D7AZ-19590-A or equivalent, to the points where the shoes contact the rear brake backing plate. Do NOT get any lubricant on the lining.
- Determine the inside diameter of the brake drum braking surface using Brake Adjustment Gauge D81L-1103-A or equivalent.
- Adjust the brake shoe and lining diameter to fit the gauge. Line up the brake shoes and linings vertically so that the flats on the bottom of the rear brake shoes and linings are aligned approximately 0.05 in. (1.5mm) above the bottom of the brake shoe and lining abutment plate before setting the gauge diameter. Hold the automatic brake shoe adjusting lever out of engagement while rotating the adjusting screw. If necessary, lubricate. Make sure the adjusting screw rotates freely.
- Rotate Brake Adjustment Gauge D81L-1103-A or equivalent around the rear brake shoe and lining to ensure proper seating.
- Install the brake drum, as outlined later in this section.
- Install the tire and wheel assembly, then install the wheel cover and nut covers, as applicable.
- After the rear brake shoes and linings have been properly adjusted, check the operation of the brakes by making several stops from varying forward speeds.
