Corp. Ref. No. 975003
Date April, 1989
SUBJECT: PARKING BRAKE ADJUSTMENT
MODELS AFFECTED: 1987-1988 CIMARRONS
The service procedure for adjusting the park brake has been revised because of an increase in the number of teeth in the park brake ratchet mechanism. This change improves the "feel" of the park brake while applying it.
The only change to the service procedure is the number of clicks the brake is applied before the adjustment is made.
Revised Procedure:
1. If necessary (for example: the drums were turned or brake shoes were replaced), adjust rear brakes as described in Section 5C2 of the Service Information Manual.
2. Lift parking brake lever to five ratchet clicks.
3. Raise vehicle and suitably support. Refer to Section OA of the Service Information Manual.
NOTICE: To prevent damage to the threaded parking brake adjusting rod when servicing the parking brake, clean and lubricate the exposed threads on each side of the nut.
4. Tighten adjusting nut on parking brake cable until the right rear wheel can just be turned rearward with two hands but cannot be turned forward.
5. Release parking brake. Rear wheels should now turn freely in either direction with no brake drag.
6. Lower vehicle.
