The brake disc (or rotor) is the rotating component of a wheel’s disc brake system, against which the brake pads press to create friction and stop the vehicle. It is typically made from gray iron, a type of cast iron known for its durability and heat dissipation properties.
Disc designs vary, with some being solid while others feature internal vanes or fins that help dissipate heat more efficiently. Ventilated discs are commonly used in high-performance vehicles and on the front wheels, where greater braking force is needed. This design helps reduce heat buildup and improves overall braking performance.
