The brake disc, also known as a rotor, is the rotating component of a wheel’s disc brake system, against which the brake pads press to slow or stop the vehicle. Typically made from gray iron, a type of cast iron, it plays a critical role in braking performance and safety. The design of the disc varies depending on the application—some are solid, while others feature internal vanes or fins to improve heat dissipation. This "ventilated" design is especially common in front disc brakes of heavier vehicles, where heat management is essential for consistent braking power and durability.
