Parking Brake System: Adjustments

PARK BRAKE ADJUSTMENT

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.

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. Pull park brake lever to first click.
2. Raise vehicle on hoist to a comfortable working height.





3. Tighten adjuster nut until tight-to-moderate drag is felt at both rear wheels when turned by hand.

NOTICE: After installation of any new park brake system component(s), the park brake system must be set prior to performing final park brake adjustment. To set park brake system after performing initial adjustment, pull up on park brake lever three or four times with approximately 265 Nm (60 lbs.) of force. It will require approximately 265 Nm (60 lbs.) of force to reach the twelfth or thirteenth click position after initial adjustment.

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

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