The brake disc, also known as the rotor, is a critical component of a vehicle's disc brake system. It is designed to work with brake pads to slow down or stop the vehicle by converting kinetic energy into heat through friction. Typically made from gray iron, this material offers excellent thermal conductivity and wear resistance, making it ideal for high-performance braking systems.
Disc designs can vary, with some being solid while others feature vented structures with fins or vanes that help dissipate heat more efficiently. Ventilated discs are commonly used in front wheels due to their higher load and heat generation. The design of the disc is crucial for ensuring optimal braking performance, especially in heavy-duty vehicles or those driven under demanding conditions.
