The causes of parking brake system failure are: 1. Parking brake failure, the main reasons for failure are excessive clearance between the friction plate and the brake drum, oil stains on the friction plate and brake drum, severe wear of the friction plate, exposed rivets, and surface hardening causing slippage; 2. The parking brake control lever cannot be fixed. When braking with the parking brake, after pulling the parking brake control lever to the braking position and releasing it, it cannot be fixed in the braking position. The parking brake is generally called the handbrake, and its function is to provide resistance to the car when parking to prevent the car from rolling. The parking brake is also known as the handbrake or the parking gear in automatic transmissions, which locks the drive shaft or rear wheels.
