@my5thmopar, what about my post do you disagree with. Just posting a disagree does not help anyone. No hard feelings, just curious! Maybe I made a mistake!
@Dana67Dart It's called fat finger on iPhone. I think you gave sound advice. But, I will say just because the reservoirs are different sizes doesn't mean it is a disk/drum. He needs to check for the residual valve. I've never had much luck with gravity bleeding anyway. Air in system is my guess. If I was doing it, I would block off MC for rear and see if I could get a hard pedal. Basically eliminate front vs back.
