The pedal must be free from corrosion and lubricated for correct operation. The pedal must be returned to the released position without sticking or binding. If a problem is present, check the cable routing for binding or misadjusted cables.

The cable tension is self adjusting. However, during normal brake lining wear, it is possible that the cable tension may need adjustment due to the increased pedal travel. If the park brake requires adjustment, check for the following conditions:

Important: To prevent damage to the threaded adjusting rod when servicing the park brake, perform the following procedure:

•	Before attempting to turn the adjusting nut, clean the exposed threads on each side of the nut.

•	Lubricate the threads of the adjusting rod before turning the nut.

1. Block the front wheels.
2. Raise and support the rear axle with safety stands. Refer to Lifting and Jacking the Vehicle in General Information.
3. Place the park brake pedal to the FULL up position.



4. Measure the threads on the equalizer. Adjust the threads to the following specifications:

•	Passenger/Cargo to 13 mm (0.511 in)

•	Cutaway/Upfitters to 21 mm (0.826 in)

5. Verify that the vehicle will hold position with the park brake pedal depressed.
6. If additional adjustments need to be made, rotate the adjuster nut using 5 mm (0.196 in) increments until the rear wheels obtain a moderate drag.
7. Back off the adjuster nut until the rear wheels are free from drag.
8. Verify that the vehicle will hold position with the park brake pedal depressed.
9. Lower the vehicle.
10. Unblock the front wheels.
