Brake Shoe: Adjustments
The hydraulic rear drum brakes are self-adjusting and require a manual adjustment only after the brake shoes have been relined, replaced or when the
length of the adjusting screw has been changed while performing some other service operation.
NOTICE: When adjusting the rear brake shoes, check the parking brake cables for proper adjustment. Make sure that the equalizer operates
freely with the shoes centered on the backing plate.
1. Raise and support vehicle.
2. Remove tire and wheel assembly.
3. Remove brake drum.
4. Apply a small quantity of caliper slide grease to points where the shoes contact the backing plate, taking care not to get lubricant on linings.
Brake Adjusting Gauge
5. Determine inside diameter of the drum braking surface using a brake adjustment gauge.
6. Adjust the brake shoe diameter to fit the gauge. Line the brake shoes up vertically so that the flats on the bottom of the brake shoes are aligned
approximately 1.5 mm (0.05 inch) above the bottom of the brake shoe abutment plate before setting the gauge diameter. Hold automatic adjusting
lever out of engagement while rotating adjusting screw. Lubricate adjustment screw threads if necessary.
NOTICE: Make sure adjusting screw rotates freely.
7. Rotate brake shoe gauge around brake shoes to ensure proper setting.
8. Install drum.
9. Complete adjustment by applying brakes several times. Brakes should be applied with a minimum of 33.8 Nm (25 ft lb) force.
10. After brake shoes have been properly adjusted, check operation of brakes by making several stops from varying forward speeds.
