Air Disc Rotors
Marathon's air disc rotors are manufactured to OE thickness specifications to resist warping and cracking issues caused by high temperature applications. The rotors feature an optimized venting design and maximized heat sink to further enhance their thermal resistance properties. These rotors are manufactured in an ISO 9000/TS16949 certified plant and are geometrically tested for design, metallurgical composition, hardness and balance. In addition, the rotors undergo a thermal integrity test at high loads. The resulting DiscStar rotor used with a DiscStar pad will provide smooth stopping and a longer service life to lower your maintenance costs.
Marathon's DiscStar family of air disc brake pads now feature 100% copper-free formulations and in complete compliance with applicable state and federal regulations as part of the Copper-Free Brake Initiative.
