A brake pad is a crucial component of a vehicle's braking system. It is made of friction material and is located within the brake caliper. When the driver presses the brake pedal, the brake pads are pressed against the brake rotor, creating friction that slows down or stops the vehicle. Brake pads come in various types, including ceramic, semi-metallic, and organic, each offering different performance characteristics. Regular inspection and replacement of brake pads are essential for maintaining safe braking performance and ensuring the longevity of the entire braking system.
