What's wrong?
The relay valve in the parking brake air system on 2022-2023 Kme Redundant Predator fire trucks helps route air pressure so the park brake applies and holds the truck when parked. In an air brake system, the valve is part of the control path between the driver's park-brake command and the rear brake hardware. The truck depends on that valve to send the right signal at the right time.
On affected trucks in recall 24V363, the wrong relay valve was installed on tandem rear axle trucks. That mismatch can keep the rear park brake from engaging when the driver sets it. If the park brake does not apply, the truck can roll away after it is parked. Kme says the final root cause remained under investigation, and the fix is to install the valve the design called for.
There is no warning sign before failure. Treat a park brake that does not hold the truck as a service problem and keep the truck secured until the correct valve is installed.
