Can the protection valves be removed and cleaned internally, or do they need to be replaced if leaking by?

My coach's air tanks have always gone to  zero after about 1.5 days. I know for a fact my entire air system had the dreaded white dust just about everywhere. I have been slowly removing,cleaning, etc all parts of the air system now for a few years. If the tanks are supposed to hold air indefinitely due to the protection valves, I surely want to take the time to clean or replace. Probably also the treadle valve

The valves are not expensive, not worth the labor to repair.

1. Is the brake treadle valve rebuild-able,
2. or one of those best to just replace?
3. If replace, anyone got the part number?
4.Guessing not a 1 size fits all.

1. Yes
2. depends on your skill and $ availability
3. refer to #4
4. Correct. This is one thing that you get the part number off the valve and get the rebuild kit for that valve.

There should be a metal tag on the treadle valve. Take that number to a truck brake parts dealer and they can give you the correct one. I always just replaced the complete valve. They come as rebuilt.
