The brake disc, also known as a rotor, is the rotating component of a disc brake system that works with the brake pads to slow or stop the vehicle. It is typically made from gray iron, a type of cast iron known for its durability and heat resistance. The design of the disc can vary, with some being solid while others feature internal vanes or fins to improve heat dissipation. This "ventilated" design is commonly used in high-performance or heavy-duty applications, especially on front wheels where more braking force is required.
