Caution: Avoid taking the following actions when you service wheel brake parts:

   • Do not grind brake linings.
   • Do not sand brake linings.
   • Do not clean wheel brake parts with a dry brush or with compressed air.
Some models or aftermarket brake parts may contain asbestos fibers which can become airborne in dust. Breathing dust with asbestos fibers may cause serious bodily harm. Use a water-dampened cloth in order to remove any dust on brake parts. Equipment is available commercially in order to perform this washing function. These wet methods prevent fibers from becoming airborne.

  1. Raise the vehicle and support the vehicle with safety stands. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Remove the adjusting hole plug in the rear brake backing plate.
  3. Turn the rear brake shoe adjuster counterclockwise until the wheel can just be turned by hand. The rear brake drag should be equal at both wheels.
  4. Back off the rear brake shoe adjuster 33 notches.

    5. Important: Brakes should have no drag after the adjuster has been backed off about 15 notches. If a heavy drag is present, refer to Park Brake Cable Service/Adjustment in Park Brake.
