Parking Brake Rear Shoe Adjustment
1. Raise and safely support the vehicle.
2. Completely unscrew one wheel stud on each rear wheel. Turn the wheel until the tapped hole is located at the adjuster.
3. Turn adjusting screw with a screwdriver until the wheel is no longer able to turn. Then back off the adjusting screw 12 notches.
4. Reinstall the wheel studs.

Parking Cable Adjustment
1. Lift off the trim cover around the parking brake lever.
2. Using Special Tool 34-1-030 or a 9mm wrench and 11mm deep socket on a ratchet, release the lock nuts and completely loosen the cables.
3. Once complete, uniformly tighten the cable adjusting nuts. The cables should be adjusted as follows:
a. Apply two teeth of the parking brake cable and turn the adjusting nuts until braking action begins.
b. Release the parking brake lever and confirm it is possible to turn the wheels easily.
c. Switch on the ignition and confirm the parking brake indicator light is OFF.
