When you press the brake pedal, your vehicle's braking system relies on its pads. These soft and absorbent components clamp onto the rotor to reduce or stop its spinning velocity, thus enabling your car to come safely to a halt. Additionally, their specific friction coefficient produces heat when pressed against the disc so that it can effectively slow down your automobile. The pads are usually made of metal plates with friction materials bonded or riveted. The most common friction material used in brake pads today is semi-metallic, though other types, such as organic and ceramics, are available. Each type has advantages and disadvantages depending on budget, driving style, and performance needs.
As pressure is applied to the brakes, hydraulic fluid from the master cylinder flows through channels in the caliper and pushes against pistons that compact the pads onto either side of a rotor. With these two components closer together, friction produces an opposing force that slows down their motion – slowing your vehicle until it comes to a complete stop.
