What Causes a Car's Handbrake to Fail to Hold?

[Malia]

The reasons why a car's handbrake fails to hold include brake fluid leakage and worn brake discs. Specific causes are as follows: Brake fluid leakage: It is necessary to check the brake fluid. Leakage or insufficient brake fluid can result in the handbrake failing to hold. The braking system mainly consists of several parts: the energy supply device, control device, transmission device, and brake. The primary function of the braking system is to decelerate or even stop a moving car, maintain a stable speed for a car going downhill, and keep a stationary car from moving. Worn brake discs: Accompanied by body shaking or abnormal noises when braking, this is due to the brake discs becoming thin or foreign objects entering the brake pads. Uneven surfaces on the brake discs can cause sharp metallic friction sounds when braking, as well as insufficient braking force, longer braking distances, and a softer brake feel.
