The brake disc (or rotor) is the rotating part of a wheel's disc brake assembly, where the brake pads are pressed against to create friction and stop the vehicle. Typically made from gray iron, this component is essential for safe and effective braking performance. The design of the disc can vary—some are solid, while others feature internal vanes or fins to improve heat dissipation, especially in high-performance or heavy-duty vehicles. Ventilated discs are commonly used on front wheels due to their greater load and heat generation.
