Parking Brake System: Adjustments

The rear drum brakes have self-adjusting shoe mechanisms that assure correct lining-to-drum clearances at all times. The automatic adjusters operate only when the service brakes are applied.
Although the brakes are self-adjusting, an initial adjustment is necessary after the brake shoes have been replaced, or when the length of the star wheel adjuster has been changed during some other service operation.


1. Jack up both rear wheels.
2. On hand operated parking brakes, apply parking brake three to five notches and on foot operated apply two notches.
3. Tighten adjusting nut until right rear wheel can just be rotated rearward but is locked when forward rotation is attempted.
5. Release parking brake and check to ensure rear wheels rotate freely in either direction with no brake drag.
