Marathon Brake Systems has developed a complete line of DiscStar air disc brake rotors for a variety of heavy-duty applications, including on-highway trucks and trailers, motorcoaches, transit buses, and school buses.

The DiscStar air disc brake rotors are manufactured to OE thickness specifications to resist warping and cracking issues caused by high temperature applications, according to a news release from the company. The rotors also feature an optimized venting design and maximized heat sink to further enhance thermal resistance properties.

Engineered to ECE R90 European standards, the DiscStar rotors are manufactured in an ISO-certified plant and are geometrically tested for design, metallurgical composition, hardness, and balance. The rotors also undergo a thermal integrity test at high loads. When used in combination with Marathon's DiscStar air disc pads, the rotors can reportedly provide smooth stopping and a longer service life to lower a fleet's maintenance costs.
