The braking system is one of the most important components of each vehicle, as it is responsible for your safety. The braking system is comprised of the main brake (pedal) and the parking brake (hand brake). When you press the brake pedal with your foot, it generates pressure which is transmitted by means of brake hoses to the brake callipers/pistons, which exert pressure on the discs/drums. This pressure causes the car to decelerate or stop. The parking brake operates through a system of cables controlled by means of a lever (which you pull with your hand) or an electric motor. The handbrake pull is transformed into the braking force of the wheels.
