Park Brake Adjustment - Drum Brakes

PARK BRAKE ADJUSTMENT
DRUM BRAKES

NOTICE: On new vehicles (less than 50 miles) and on vehicles equipped with rear drum brakes that have been serviced, before performing Park Brake Adjustment procedures, apply and release the brake pedal 20 times. This allows the adjuster to position the brake shoes and prevents premature wear of the brake linings due to improper park brake adjustment.





1. Remove park brake boot from console by squeezing sides of boot while pulling upward.

CAUTION: MAKE SURE VEHICLE IS PROPERLY SUPPORTED AND SQUARELY POSITIONED ON THE HOIST. TO HELP AVOID PERSONAL INJURY WHEN A VEHICLE IS ON A HOIST, PROVIDE ADDITIONAL SUPPORT FOR THE VEHICLE ON THE OPPOSITE END FROM WHICH COMPONENTS ARE BEING REMOVED.

2. Raise vehicle on hoist so wheels spin freely.





3. Pull park brake lever to third click.
4. Tighten adjuster nut so there is heavy drag to no rotation, equal to both rear wheels.

NOTICE: After installation of any new park brake system component(s) (e.g., park brake lever, cable, drum brake shoes, adjuster, lever, rear disc brake caliper, etc.), the park brake system must be set prior to performing final park brake adjustment. To set the park brake system after performing initial adjustment, pull up on the park brake lever three or four times with approximately 445 N (100 lbs.) of force.

5. Apply and release park brake several times. There should be no drag when park brake lever is in the rest position.
6. Pull park brake lever to third click. There should be heavy drag at both wheels when turned by hand.
7. If necessary, repeat steps 3 through 5 until adjustment is correct.

IMPORTANT: If both rear wheels do not exhibit similar drag in steps 5 through 7, check for damaged or incorrectly installed rear disc or drum brake assembly components, park brake cables, and/or park brake lever assembly. Correct as necessary; return to step 3 of this procedure.





8. Install park brake lever boot.
9. Lower vehicle from hoist.
