So this is nifty, the best explanation of how the brake/pilot parts of the pump work have come from the patent that JD filed, that makes more sense, its a closed circuit system, So the issue seems to be super low pressure. Now the brake pump that's installed looks nothing like any of the new/used ones on the market (matches the parts book) this one is a little strange. I'm going to go and get a data tag photo and see just what's going on. Whereas it was pissing brake fluid into the front axle and the rear axle brakes were wasted, I'm starting to wonder if they turned the pressure down so its just enough to run the pilot functions. More exploring and fun.
