The brake disc (or rotor) is the rotating part of a wheel's disc brake assembly, against which the brake pads are applied. Typically made from gray iron, it is a crucial component in the braking system of vehicles. The design can vary—some are solid, while others are ventilated with fins or vanes that help dissipate heat. Ventilated discs are commonly used on front wheels due to higher heat generation. This design ensures better cooling and improved performance under heavy use.
