92 Ram van brake nightmare

I'd look at it from a stand point that something is acting like a check valve. Sounds like presure builds up in it and doesn't get to blead back for one reason or another. Could replace the proportioning valve also. I'm foggy on how those work though. Sure sounds like you almost have it though. You could also probably ditch the ABS. I'm shooting blind on this.. take some parts off a a non-abs model and slap em in.

Installed a new MC and went to bleed system...nothing at the rt front(source of the problem). One source told me to loosen the line and if it leaked it was pumping...loosened it and got nothing. Went back to old MC and all 4 were able to bleed and believe me I ran almost a half quart of brake fluid out and thru the system under brake pressure.
Test drive told me that the same problem is there after 10 to 12 city blocks. Brakes locked up on the rt front.
I am now under the impression and frustration that the problem lies in the ABS or proportioning valve... now when I was under the van today I did notice a bit of old(not fresh...a bit crusted) seapage on one of the braking system valves(two stacked together) located just below the MC on the frame rail.
