Parking Brake Shoe Adjustment
Check the operation of the parking brake system with the vehicle on a hoist and the parking brake control fully released. Check for any damaged cables and install new components as necessary. Check the rear brake adjustment. See BRAKE SHOES .
Using Brake Adjustment Gauge (D81L-1103-A), measure inside diameter of drum portion of rear brake disc or brake drum. On F150 Pickup and F150 Heritage Pickup with drum brakes, using parking brake adjuster screw, adjust parking brake shoe and lining until they drag against parking brake drum. On models with rear disc brakes, adjust parking brake shoe and lining to 0.020" (0.51 mm) less than drum measurement. Replace the parking brake shoes if the linings have worn to within 0.04" (1.0 mm) of the shoe. On all models, check the parking brake by depressing the parking brake control pedal. The parking brake must be fully set by applying pressure to the pedal before it reaches a mechanical stop. If not as specified, install a new parking brake control/cables as necessary.
