Instead of measuring the shoes and drum to set the rear brake adjustment you can also adjust them out slowly until a light scraping sounding is heard when the drum is on and spinning it by hand.
1. Raise and support the vehicle
2. Remove the lug nuts and the wheel and tire assembly.
3. Remove the two brake drum screws and remove the brake drum.
4. Use Brake/Clutch/Service Vacuum 164-R36OO or equivalent to remove brake dust and dirt from the brake assemblies.
Shoe Hold Down Spring
5. Push, turn, and remove the brake shoe hold-down springs.
6. Remove the (A) brake shoe retracting spring and the (B) anti-rattle spring and remove the brake shoes and linings.
7. Remove the parking brake link spring.
8. Pull the parking brake actuation lever through the slot in the brake backing plate.
NOTE: If new rear brake shoes and linings are being installed, resurface the brake drums to remove glazing and to ensure an equal friction surface from side-to-side. Resurfacing will also correct out-of-round and bell conditions.
Using Brake Drum Micrometer
1. Use a brake drum micrometer to measure the braking surface diameter. If it has worn more than the maximum diameter, shown on the outside of the brake drum, replace the brake drum
2. If the rear shoes and linings are to be reused, inspect and measure the thickness. If the shoes are worn beyond the minimum thickness specification, replace them.
1. To install, reverse the removal procedure.
2. Measure the brake drum with Brake Adjustment Gauge.
Measuring Brake Shoe Adjustment
3. Put the Brake Adjustment Gauge on the brake shoes and adjust the brake shoes.
NOTE: Tighten the drum retaining screws to 10-14 Nm (89-123 inch lbs.).
NOTE: Tighten the lug nuts in the specified sequence to 89-117 Nm (66 - 86.7 ft. Lbs.).
