The brake disc (or rotor) is the rotating component of a wheel’s disc brake system, where the brake pads press against to create friction and slow down the vehicle. Typically made from gray iron, it is known for its durability and heat dissipation properties. Some discs are designed with internal vanes or fins to improve cooling, making them ideal for high-performance vehicles or heavy-duty applications. The choice between solid and ventilated designs depends on the vehicle's weight, power, and braking demands.
