First how is the fluid in the MC reacting after you release it from the a pumped up hard pedal? Does it ..fountain.. in the reservoir as was mentioned as a symptom to check in your first post? If so that is a sign of air still in the system. When you are testing the pedal by pumping it up is the engine running or not? Should be able to check the master cylinder for leak- by in the following manner. Purchase a flare line plug of cut a short end ..not much more that an inch. of old line the proper size to fit in the master cylinder fitting. Pinch the line shut and braze it to seal it. The gravity bleeding while you are attaching it should be good enough to test it once installed. Obviously, with the plug installed the pedal should not bleed down. If the MC tests okay for no bleed-down I would suggest pulling the vacuum supply hose off at the Hydro-vac and check for fluid. If all else fails I would recommend at least trying a couple good bleed cycles at each wheel with a pumped up pedal and the engine running to see if you can move the air out with the higher pressure built up.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
