What is the Difference Between a Foot Brake and a Hand Brake?

[SanHailey]

Hand brake and foot brake differ in the following aspects: 1. Different usage scenarios—the hand brake is used after the vehicle has stopped, while the foot brake is used while the vehicle is in motion to bring it to a halt or decelerate. 2. The hand brake can be further categorized into electronic hand brakes and mechanical hand brakes. Both serve the same purpose and are used in the same situations, but the electronic hand brake is more convenient to operate, whereas the mechanical hand brake is more stable and reliable. The working principle of the braking system is as follows: 1. The braking system works by generating immense friction to convert the vehicle's kinetic energy into thermal energy. 2. Energy cannot be created or destroyed; it can only be transformed from one form to another or transferred from one object to another, with the total amount of energy remaining constant during the process. 3. During acceleration, a car converts chemical energy into thermal and kinetic energy, and when braking, the braking system converts the car's kinetic energy back into thermal energy, which is then dissipated into the air.
