The brake disc, also known as the rotor, is a crucial 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 create friction and slow down or stop the vehicle. Typically made from gray iron, it is designed to withstand high temperatures and provide consistent braking performance. There are two main types of brake discs: solid and ventilated. Ventilated discs feature internal vanes or fins that help dissipate heat more effectively, making them ideal for high-performance or heavy-duty vehicles. Solid discs, on the other hand, are often used in lighter applications where heat dissipation is less critical. Our products are manufactured using advanced casting techniques and high-quality raw materials. The material used meets the G3000 standard, ensuring durability and reliability. Each brake disc undergoes rigorous testing, including dimensional checks and surface finishing, to ensure precision and quality. Our Advantages:
