I'd check the treddle valve next, it might be leaking a small amount of air through. When you disconnect the signal line going into the relay valve, is there air coming through that line?( tires chocked, brakes released, pedal not depressed )

Take all the service brake lines off the relay or off the brake pots then release the maxi brakes the one that leaks is the problem. Remove even the new ones, I have seen new ones leak, the problem is in one of the piggy back.
Just a thought!
