The brake disc, also known as the rotor, is a key component of a vehicle’s disc brake system. It rotates with the wheel and provides the surface against which the brake pads press to slow or stop the vehicle. The material is typically gray iron, a type of cast iron known for its durability and heat resistance.
Disc designs vary, with some being solid and others featuring fins or vanes to improve cooling and heat dissipation. Ventilated discs are commonly used in high-performance or heavy-duty applications, such as on front wheels, where more effective heat management is essential.
