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 clamped by the brake pads to create friction and slow down or stop the vehicle. Typically made from gray iron, it is designed to withstand high temperatures and maintain performance under heavy braking conditions. The design can be solid or ventilated, with the latter being more common in front wheels due to higher heat dissipation needs. Our Advantages:
