    The brake disc (or rotor) is the rotating part of a wheel's disc brake assembly, against which the brake
    pads are applied. The material is typically gray iron,a form of cast iron.

    The design of the discs varies somewhat. Some are simply solid, but others are hollowed out with fins
    or vanes joining together the disc's two contact surfaces (usually included as part of a casting process).
    The weight and power of the vehicle determines the need for ventilated discs.The "ventilated" disc
    design helps to dissipate the generated heat and is commonly used on the more-heavily
    loaded front discs.

    Our advantage as below:
    1.-Professional Manufacture ,high-volume environmental foundry electric stoves and foundry
    production line,output reach 5000 tons per month.
    2.-Long Service Life and quality warrantee period & Low noise for brake discs.
    3.strictly testing and ways for discs and drums dynamic balance.keep the products stable balance
    during driving.
    100% test brake discs' crucial dimension inspection and machining surface.
