The brake disc, also known as the rotor, is the rotating component of a wheel's disc brake system that applies pressure against the brake pads. It is typically made from gray iron, a type of cast iron. The design can vary, with some discs being solid while others are ventilated with fins or vanes to improve heat dissipation. Ventilated discs are commonly used on front wheels due to their higher load and heat generation. These designs help manage the heat produced during braking, ensuring better performance and longevity.
