Why Can the Car Still Move When the Handbrake Is Engaged?

[AylaFitz]

The reason the car can still move when the handbrake is engaged is that the handbrake locks the rear wheels. For front-wheel-drive vehicles, the car can still drive after the handbrake is pulled, while for rear-wheel-drive vehicles, if the engine's horsepower is sufficiently strong, the rear wheels may still move when the accelerator is pressed despite being locked. Precautions for using the handbrake: 1. Avoid pulling it too tightly to prevent the brake function of the handbrake cable from deteriorating; 2. For automatic transmission vehicles, the handbrake should be engaged before shifting to P; 3. The handbrake cannot replace the foot brake during high-speed driving; 4. Do not forget to engage the handbrake when stuck on a slope. The handbrake, also known as the auxiliary brake, uses a steel cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake can cause the steel cable to undergo plastic deformation, which is irreversible. Prolonged use will reduce its effectiveness and increase the handbrake's travel distance.
