Don, did you use speed bleeders? Hopefully you had a spare set of hands to open and close the bleed valves at the calipers while you worked the pedal. The last thing you could do is bleed the MBC while its installed by opening the lines at the MBC while working the pedal.
Your problem sounds exactly like mine.
It took the better part of 45 minutes for 3 of us to do my brakes. Before that it took me the better part of 3 weeks by myself to get nowhere. Its a process for sure. I went threw many a hammer and verbage before mine started to work.
Either way I am FOS.
