1. Handbrake

A handbrake (also known as a parking brake or emergency brake) is a secondary braking system in a vehicle that helps keep it stationary when parked. It's usually operated manually by the driver—either through a lever, pedal, or button.

  • Holds the vehicle in place when parked, especially on slopes.
  • Acts as a backup brake in case the main brakes fail (in emergencies).
  • Useful when stopping briefly on hills (e.g., at a red light) to prevent rolling.
  • It's not meant for slowing down while driving (unless it's a true emergency).
  • It should be released before driving — driving with it on can damage the brake system.
  • Types of Handbrake Systems:
    • Manual lever – traditional handbrake located between the front seats.
    • Foot-operated pedal – found to the left of the driver’s footwell in some vehicles.
    • Electronic parking brake (EPB) – activated by a button or switch, often in modern cars.
