Parking Brake System: Adjustments

Parking Brake Inspection and Adjustment

Inspection

1. Press the parking brake pedal (A) with 294 N (30.0 kgf, 66.1 lbf) of force to fully apply the parking brake. The parking brake pedal should be locked within the specified number of clicks.









2. Adjust the parking brake if the pedal clicks are not within the specification.

NOTE: Minor parking brake pedal adjustments (1 to 2 clicks) can be made with the adjusting nut (see parking brake minor adjustment). If a larger adjustment is required, follow the major adjustment procedure using the adjuster nut at the parking brake drum (see parking brake major adjustment).
After installing new parking brake shoes and/or new brake disc/drum, make sure you drive the vehicle for "break-in" Procedures.
