To the original poster are you running reproduction shoes? If so you need to grind .020" off the tabs of the shoes where the cylinder pistons push against. The reproduction shoes are made with the tab too long causing the cups to push in too far into the wheel cylinder. We include a note dictating such in all the shoes we sell. This is only a issue if your drums measure less than around 12.030". What exactly is your issue in not getting them to bleed right? Soft pedal? If it is a soft pedal use good reproduction cylinders and check out the shoe issue I mentioned and you'll be set.

No need as others have mentioned to bench bleed a master cylinder. .... Check for minimal leaks as well! Are you using copper washers between the front hoses and the cylinders? if not, do so.
