You keep mentioning how this truck was used near the ocean, have you seen any other (other than the relay valves) evidence of "internal" corrosion? The compressor must have sucked a lot of salt laden air in that environment.
Is your parts truck free of this kind of corrosion?

I'm looking at an air line diagram from TM 9-2320-272-24-4 and see a lot of valves....why is a "limiting" valve used for the front brakes and "relay" valves used for the rear, they seem to serve the same purpose? The system is very different from the 100% air system on my 8x8, so I'm just wondering.
