What is the difference between handbrake and footbrake?

[DiSilas]

The differences between handbrake and footbrake are as follows: 1. Different tires affected: The footbrake applies braking to all four wheels; the handbrake only affects the rear wheels. 2. Different principles: The footbrake distributes hydraulic fluid from the master cylinder to the wheel cylinders at each wheel, then pushes the brake pads to rub against the brake discs (or drums), achieving deceleration or stopping; the handbrake uses a steel cable connected to the rear brake shoes to apply braking force. 3. Different braking force: The footbrake provides greater braking force and includes safety features such as brake force distribution and brake override; the handbrake offers smaller braking force without safety configurations. 4. Different usage scenarios: The footbrake is generally used for braking or slowing down while the vehicle is in motion; the handbrake is used after the vehicle has stopped to prevent it from rolling away.
