Parking Brake System: Adjustments

1. Cycle brake system as follows:
a. Apply service brake with a pedal force of 150 lbs. and release.
b. Fully apply parking brake using approximately 125 lbs. of force on final stroke, and release.
c. Apply and release parking brake two additional times as described above.
2. Check parking brake pedal assembly for full release by turning ignition on and inspecting brake warning light. Light should be off. If brake warning light is on and parking brake appears to be fully released, operate the manual pedal release lever and pull downward on front park brake cable to remove slack from pedal assembly.
3. Raise and support vehicle.
4. Check parking brake levers on rear calipers. Levers should be against the stops on caliper housing. If levers are not against stops, check for binding in rear brake cables and position levers against stops.
5. Tighten parking brake cable at adjuster until either left or right lever begins to move off of stop.
6. Loosen adjuster until lever which moved off of stop in step four is again resting on stop. Both levers should be resting on caliper stops after completing this step.
7. Operate parking brake several times to check adjustment. A firm pedal feel should be obtained by pumping pedal less than one stroke.
8. Inspect left and right caliper levers. Both levers must be resting on stops after adjustment of parking brake.
9. Check operation of parking brake. If possible, place vehicle on a grade and check parking brake holding ability.
