## What the record says

- **Product**: HALDEX INVERSION RELAY VALVE - Recall 24E011000
- **Reason**: 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." Delayed parking brake engagement can result in unintended vehicle movement, increasing the risk of a crash.
