Marathon Brake Systems recently applied its braking expertise to develop a complete line of DiscStar air disc brake rotors for a variety of heavy duty applications.
Marathon introduced its first DiscStar air disc pad for transit applications in 2003. Marathon’s new air disc rotors are manufactured to OE thickness specifications to resist warping and cracking issues caused by high-temperature applications. DiscStar air disc brake rotors are designed to address a wide range of aftermarket air disc brake applications, including on-highway trucks and trailers.
DiscStar rotors feature an optimized venting design and maximized heat sink to enhance their thermal resistance properties, the company said. DiscStar rotors are engineered to ECE R90 European standards and feature a pillar venting design for faster cooling, less “heat checking” and cracking. Marathon’s 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.
Utilizing Marathon’s DiscStar rotors in combination with proven DiscStar pads will provide smooth stopping and a longer service life to lower a fleet’s maintenance costs, the company said.
Marathon air disc pads have been proven performers for more than 15 years in a wide range of applications. DiscStar Pad and rotor compatibility has been engineered into both the friction material as well as the rotor and verified with RP628C and SAE J2115 wear testing standards. Marathon has developed specific pad formulations and rotor designs for a wide range of on-highway, severe duty and other applications.
