Diagnosis

With the vehicle on an appropriate hoist, check the rear wheels for brake drag. The wheels should rotate freely. If the wheels do not rotate freely, apply and release the parking brake several times. Inspect the parking brake cables for freedom of movement and complete release of parking brake apply forces. If the movement of the parking brake cable(s) is restricted, perform repair PROCEDURE A.

Inspect the rear brake linings for wear. If right and left wheel brake linings are worn approximately the same, follow normal rear brake shoe replacement procedures as outlined in the appropriate Service Manual. If the wear of the right and left wheel brake linings differ significantly, manually pull the wheel caliper with the linings that have the most wear toward the outside of the vehicle so the caliper piston will be retracted. If the caliper piston does not retract, perform repair PROCEDURE B. If the caliper does move freely, follow normal rear brake shoe replacement procedures as outlined in the appropriate Service Manual.
