汽车手刹的作用是什么？

最佳答案

Handbrake is an auxiliary brake system primarily used in vehicles to prevent车辆 during braking and stopping, helping the driver control lateral movement (溜动). The hand brake is also known as a braking auxiliary lever or wheel brake. It connects via steel ropes or wires called tension lines to the rear braking drum. This design allows the vehicle's brakes to apply force directly to the wheels.

Long-term use can cause the tension lines to become permanently stretched, reducing the effectiveness of the hand brake over time. The length of the tension line used may also increase with prolonged use to maintain optimal braking performance. Regular inspection and maintenance are recommended to ensure the hand brake operates at its peak efficiency and prevent further degradation.
