The brake disc, also known as the rotor, is a critical component of a vehicle’s disc brake system. It is the part that rotates with the wheel and is pressed against by the brake pads to slow or stop the vehicle. The material used is typically gray iron, a type of cast iron known for its durability and heat resistance.
Disc designs can vary—some are solid, while others feature internal vanes or fins to improve cooling, especially in high-performance or heavy-duty vehicles. Ventilated discs are commonly used on front wheels due to their higher load and heat generation. This design helps dissipate heat more effectively, reducing the risk of brake fade during prolonged use.
