What to Do When the Parking Brake Fails?
1 Answers
Parking brake failure can be addressed by adjusting the control lever and then the hand brake clearance. If this proves ineffective, disassemble the hand brake for inspection and repair. The parking brake, also known as the hand brake, is a manually operated brake installed in motor vehicles to stabilize the vehicle after it has come to a stop, preventing accidents caused by rolling on inclined surfaces. Common causes of parking brake failure include: 1. Insufficient brake fluid pressure; 2. Air in the brake system; 3. Excessive free travel of the brake pedal or excessive brake clearance; 4. Wear or damage to the brake master cylinder, wheel cylinder pistons, wheel cylinder tubes, or aging and deterioration of the rubber cups. To use the parking brake: With the right hand, bring the four fingers together, position the thumb opposite the fingers (tiger mouth forward), pull the control lever upward firmly until the brake indicator light on the dashboard illuminates.
