2. Physical Properties
The brake disc (or rotor) is the rotating component of a wheel's disc brake system, against which the brake pads press to slow or stop the vehicle. It is typically made from gray iron, a type of cast iron. The design can vary, with some discs being solid and others featuring vents or vanes that help dissipate heat generated during braking. Ventilated discs are commonly used on heavier vehicles or those with higher performance requirements, as they provide better cooling and reduce the risk of brake fade.
