S472-500-405-0 or S4725004050 is a genuine Meritor ABS valve package that combines a service brake relay valve with two ABS modulator valves, so the valves do not have to be installed separately. It is a 6S/4M system configuration that runs on 12V, has a crack pressure of 5.5 psi and is compatible with C, D and E Version ECUs. The package controls air to the brake chambers under anti-lock control. Air that keeps escaping from a modulator exhaust port while the brakes are applied usually points to a bad valve, since exhaust is normally expected only during an ABS event or the key-on self-test. Call Pro Gear and Transmission to confirm your ECU version and fit.
