Parking Brake System: Testing and Inspection

WARNING: Make sure vehicle is properly supported and squarely positioned on hoist. To help avoid personal injury, provide additional support to the end of the vehicle opposite that from which components will be removed.

NOTE: On new vehicles (less than 50 miles) and on vehicles 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.

ADJUSTMENT CHECK
1. Raise vehicle on hoist.

CAUTION: If both rear wheels do not exhibit similar drag in step 3, check for damaged or incorrectly installed rear disc or drum brake assembly installation of drum assembly components, park brake cables, and/or park brake lever assembly. The park brake is adjusted correctly if it meets the specifications explained in steps 2 and 3.

2. There should be no drag at rear wheels with park brake lever in rest position.
3. Pull park brake lever to 4th click. There should be heavy brake drag to no rotation at both rear wheels when turned by hand.
4. Adjust if necessary. Adjustments
