The brake disc, also known as the rotor, is a critical component of a vehicle's disc brake system. It is the part that the brake pads press against to slow or stop the vehicle. Typically made from gray iron, which is a type of cast iron, it provides durability and heat dissipation. The design can vary—some are solid, while others feature fins or vanes that help dissipate heat more efficiently. Ventilated discs are commonly used in high-performance or heavy-duty vehicles, especially on the front wheels, where more heat is generated during braking.
