Parking Brake Warning Light

The parking brake switch is incorporated in the circuit for the red warning lamp in the dash. The switch will cause the
lamp to illuminate only when the parking brakes are applied. If the lamp remains on after parking brake release, the
switch or circuit is faulty.

Parking Brake Operation

The leading cause of improper parking brake operation, is excessive clearance between the parking brake shoes and
the shoe braking surface. Excessive clearance is a result of lining and/or drum wear, drum surface machined over-
size.
In most cases, the actual cause of an improperly functioning parking brake (too loose/too tight/won't hold), can be
traced to a parking brake component.
Inspect the following when diagnosing a parking brake problem:
• Brake shoe wear
• Drum surface (in rear rotor) machined oversize
• Front cable not secured to lever
• Rear cable not attached to actuator
• Rear cable seized
• Parking brake lever not seated
• Parking brake lever bind

Parking Brake Adjustment

Adjust the parking brake only if the parking brake lever can be pulled up more than 3 notches without having an
adequate solid braking effect.
NOTE :
Excessive parking brake lever travel (sometimes described as a loose lever or too loose condition), could be the
result of worn brake shoes, improper brake shoe adjustment, or improperly assembled brake parts. A too loose con-
dition can also be caused by inoperative or improperly assembled parking brake components. Always confirm that the
parking brake components are assembled properly. Perform the following procedure to adjust the parking brake:
1. Verify the parking brake lever is in the released (down) position.
2. Raise and support the vehicle.
3. Remove the wheel mounting nuts and the rear tire and wheel assemblies.
4. Utilizing the access hole in the rotors, adjust the parking brake shoes.
5. Reach inside the vehicle and fully apply and release the parking brake.
6. With the parking brake lever in the fully applied (up) position, attempt to rotate the rear rotors by hand (to ensure
that the parking brake shoes are working properly).
7. With the parking brake lever in the released (down) position, attempt to rotate the rear rotors by hand (to ensure
that the parking brake shoes are not dragging).
8. Install both rear tire and wheel assemblies and the wheel mounting nuts.
(Tighten: Wheel mounting nuts to 110 N·m)
