Parking Brake

NOTE: If a firm parking brake pedal feel cannot be achieved, with less than one full stroke of parking brake pedal, check parking brake cable adjustment. If parking brake lever will not return to stop on caliper housing, and parking brake cable is loose or disconnected, overhaul or replace rear caliper.
  1. Press service brake pedal with about 150 lbs. (68.0 kg) of force and release. Apply parking brake 3 times with a force of about 125 lbs. (56.7 kg) and release.
  2. To ensure parking brake pedal is fully released, turn ignition on. BRAKE indicator light on instrument panel should be off. If light is off, go to next step. If light is on and parking brake appears to be fully released, depress push-to-release pedal and pull front parking brake cable downward to remove slack.
  3. Raise and support vehicle. Loosen parking brake cable adjuster. Check parking brake lever on each rear caliper. If levers are not against stops on caliper housings, check for binding in rear cables. Position levers against stops. Tighten parking brake cable at adjuster until left or right lever begins to move off stop.
  4. Loosen cable adjuster until lever that moved off stop in previous step is again resting against stop. Both levers should now be resting against stop. Operate parking brake several times to check adjustment is correct. Firm brake pedal feel should be obtained when pressing pedal less than one full stroke.
  5. Release parking brake and check that parking brake levers are resting on lever stops. Lower vehicle. Check operation of parking brake. If possible, place vehicle on a grade and check parking brake holding ability.
