Brake rotors, also known as brake discs, are an essential component of automotive braking systems found within the "Automotive Brakes Parts" category. They are mounted to the wheel hub and rotate along with the wheels. When the brake pedal is applied, the brake pads clamp down on the surface of the rotor, generating friction which slows down the rotation of the wheels, allowing the vehicle to stop. Brake rotors can be solid or vented for improved cooling and come in various sizes depending on the make and model of the vehicle. Their construction materials include cast iron, ceramic composite, and carbon-ceramic matrix, each with its unique advantages and applications. Regular inspection and maintenance are crucial to ensure their longevity and optimal performance.
