What is the braking principle of the handbrake?

[GemmaFitz]

It uses a steel cable connected to the rear brake shoes to brake the vehicle. Here is a related introduction to the handbrake: 1. Handbrake principle: The professional term for the handbrake is the auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake will cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel distance will also increase. A return spring is used in conjunction with the handbrake. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. Long-term use of the handbrake will also cause corresponding deformation in the spring. 2. Necessity of correct use: The handbrake is a frequently used system. Proper and correct use can ensure smoother operation in the future, extend its adjustment cycle, and reduce maintenance and replacement costs.
