  1. Raise and support the rear of the vehicle on jackstands.
  2.  
  3. Remove the rubber cover from the backing plate.
  4.  
  5. Insert a brake adjusting tool through the hole in the brake backing plate. Turn the toothed adjusting nut to spread the brake shoes, making contact with the brake drum.
  6.  

When adjusting the brake shoes, turn the wheel until considerable drag is felt. If necessary, hit the brake drum with a rubber hammer to align the shoes with the drum.

  1. When considerable drag is felt, back off the adjusting nut a few notches, so that the correct clearance is maintained between the brake drum and the brake shoes. Make sure that the wheel rotates freely.
