I have a 2640 that one of the brake pedal when you press on it just goes down no brakes if pump will work. When bleed brakes will work for a while. The piston for the brakes seems to be leaking fluid by it. How hard is it to take that control unit off for the brakes and take it to get rebuilt and would that be causing the brake problem
 
Cap the line going to that brake and see if the pedal stays strong,, there is a chance that the brake piston in the final drive is leaking, it takes a small JIC cap to do it .
 
I had a 2440 and it ended up being the seals on the pistons in the final drives. I'd find some caps and test like Tim says it will save a lot of time. Wish I'd of did something like that on the one I worked on.
