ZF North America, Inc. (ZF) is recalling certain park brake actuation air brake systems equipped with Haldex inversion relay valves, part numbers 9718990020 and RKN28032. An internal piston in the inversion valve may fail, delaying the engagement of the parking brake. As such, these valves fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
