Parking Brake System: Adjustments

Adjusting The Parking Brake:

NOTE: Adjustment of parking brake cable is necessary whenever the rear brake cables have been disconnected. A need for parking brake cable adjustment is indicated if the hydraulic brake system operates with good reserve, but a firm parking brake pedal feel cannot be achieved with less than one full stroke of the parking brake pedal.

ADJUST
1. Cycle brake system.
a. Apply service brake with a pedal force of approximately 660 N (150 lb.) and release.
b. Fully apply parking using approximately 550 N (125 lb.) pedal force and release.
c. Apply and release parking brake two additional times as described above.
d. Park brake light should be illuminated after park brake has been depressed two clicks.
e. Apply park brake two clicks and drive vehicle approximately 50 feet. The multi-function chime module should briefly sound a fast chime to alert drive that the park brake is on.
2. Check parking brake pedal assembly for full release by turning ignition on and inspecting "PARK BRAKE" warning light. Light should be off. If "PARK BRAKE" warning light is on and parking brake appears to be fully released, depress "push to release" pedal and pull downward on front parking brake cable to remove slack from pedal assembly.
3. Raise 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 the left or right lever begins to move off stop.
6. Loosen adjuster until lever which moved off of stop in step 4 is again resting on stop. Both levers should be resting on caliper stops after completing this step.
7. Operate park brake several times to check adjustment. A firm pedal feel should be obtained by depressing the pedal less than one full 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.
