Why does the handbrake not hold?
1 Answers
The reasons why the handbrake does not hold are: 1. Severe wear of the brake pads, requiring replacement of the brake pads. 2. If the brake pads are not the issue, then the handbrake cable may have stretched, necessitating adjustment of the handbrake cable. The professional term for the handbrake is the auxiliary brake. Unlike the principle of the main brake, it uses a steel wire cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel wire to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness, and the handbrake's travel distance will also increase. The handbrake system also includes a return spring. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. With prolonged use, the spring may also undergo corresponding deformation.
