The Knorr Bremse Rotor K038574 is a heavy-duty air disc brake rotor used on Bendix / Knorr-Bremse ADB22X and ADB225 braking systems for trucks and trailers. This U-shaped vented rotor has an overall diameter of approximately 430 mm and a disc thickness of 45 mm, with a minimum service thickness of 37 mm. The rotor height is 150 mm, with 10 threaded mounting holes on a 249.5 mm bolt circle and a pilot diameter around 220 mm to suit common commercial vehicle hubs. Manufactured from grey cast iron with high carbon G3000 material, the rotor is engineered for consistent strength, thermal stability and wear resistance in demanding on-road applications. The vented construction and OE-style vane layout support effective heat dispersion to help control cracking, heat checking and distortion under repeated braking. This rotor is supplied as an aftermarket new replacement for Bendix part number K038574 and interchanges with a wide range of OEM and aftermarket references. It is used across various heavy vehicle applications, including Great Dane trailers and International HV613 models equipped with Bendix ADB22X air disc brakes.
