Will the Car Roll Away If the Handbrake Is Engaged?

[DeLorenzo]

Under normal circumstances, if the handbrake is fully engaged, the car should not roll away. If this happens, it is mostly due to a faulty handbrake or insufficient tightness. Introduction to the Handbrake: The professional term for the handbrake is auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to apply braking force to the car. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel distance. Precautions for Using the Handbrake: The handbrake is a frequently used system. Only proper and correct usage can ensure smooth operation in the future, especially for the most common mechanical handbrakes. It is essential to follow the correct method—do not engage the handbrake before the car has come to a complete stop, as this practice is unnecessary. Using it sparingly ensures good performance, which is crucial for safety. Additionally, it can extend the adjustment cycle and reduce maintenance and replacement costs.
