The brake disc, also known as the rotor, is a crucial component in a vehicle’s disc brake system. It is the part that rotates along with the wheel and is pressed against by the brake pads to create friction and slow down or stop the vehicle. Typically made of gray iron, a type of cast iron, it provides excellent heat dissipation and durability.
Disc designs vary, with some being solid and others featuring vanes or fins that help dissipate heat more effectively. Ventilated discs are commonly used on the front wheels of vehicles due to their higher load and heat generation. The material and design of the disc play a vital role in ensuring safe and efficient braking performance.
