What is the Difference Between the Handbrake and the Foot Brake?
1 Answers
The differences between the handbrake and the foot brake are as follows: 1. Different application positions: The two brakes control the brake calipers through different mechanisms. The foot brake applies 70% of the braking force to the front wheels and 30% to the rear wheels, while the handbrake applies 100% of the braking force to the rear wheels, with no effect on the front wheels. 2. Different applicable scenarios: The handbrake is used for stopping at red lights, long-term parking, and when leaving the vehicle, whereas the foot brake is used for parking and stopping; pressing it stops the vehicle, and releasing it allows the vehicle to start, making it suitable for both driving and stopping. Additional information: 1. Foot brake: The foot brake is the vehicle's main brake, where the braking force is transmitted mechanically from the brake pedal to the hydraulic system. The hydraulic pressure of the brake fluid is then transmitted through the pipelines to the actuators on the brake discs, providing strong braking force with easy and effortless control. It is the primary braking device during normal driving. 2. Handbrake: The professional term for the handbrake is the auxiliary brake (parking brake), which operates on a different principle from the main brake. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use can reduce its effectiveness and increase the handbrake's travel distance.
