Parking Brake System: Adjustments

Parking Brake Inspection and Adjustment

Inspection
Hold center of parking brake lever grip and pull it up with 200 N (20 kg, 44 lbs) force. With parking brake lever pulled up as shown, count ratchet notches. There should be 4 - 9 notches. Also, check if both right and left rear wheels are locked firmly. To count number of notches easily, listen to click sounds that ratchet makes while pulling parking brake lever without pressing its button. One click sound corresponds to one notch. If number of notches is out of specification, adjust cable referring to adjustment procedure so as to obtain specified parking brake stroke.

NOTE: Check tooth tip of each notch for damage or wear. If any damage or wear is found, replace parking brake lever.
