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 along with the wheel and is pressed against by the brake pads to slow or stop the vehicle. Typically made from gray iron, which is a type of cast iron, it provides the necessary friction for braking.
Disc designs vary depending on the application. Some are solid, while others feature fins or vanes that help dissipate heat, making them ideal for high-performance or heavy-duty vehicles. Ventilated discs are commonly used in front wheels due to their higher load and heat generation.
