What are the common faults of the parking brake?

The common faults of the parking brake include: ineffective braking, brake failure, deviation, and dragging. The causes of these faults are: 1. Insufficient brake oil 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 piston, wheel cylinder pipe, or aging and damage of the rubber cup. The method of using the parking brake is: during operation, the four fingers of the right hand are brought together, the thumb is placed forward, the right hand is lifted forcefully to tighten the control lever, and at the same time, the brake indicator light on the dashboard lights up. The parking brake refers to the manual brake installed on motor vehicles, commonly known as the handbrake, which is used to stabilize the vehicle after it has come to a stop, preventing accidents caused by the vehicle rolling on sloping roads.
I often deal with car issues, and parking brake failures are quite common. The most frequent problems are difficulty pulling the brake or it being too hard to pull, usually due to rusted or stuck cables, especially after rainy or snowy weather. Another issue is the car still rolling after the brake is engaged, which could be caused by overly loose cables or excessively worn brake pads, resulting in insufficient friction. There are also strange noises, like squeaking or clicking, which are mostly due to worn internal components or the need for lubrication. When encountering these situations, I first check the tightness of the cables. If they're too loose, I try adjusting them, but if you're not familiar with it, it's best to visit a professional shop to avoid causing damage. Safety is crucial; if the brake fails while parking on a slope, it can be very dangerous. Therefore, regular rust prevention and inspections can save a lot of trouble.
