Master been replaced? Sounds like the master is bypassing internally .If you've gone this far, I'd replace or rebuild.

Have you adjusted the brakes shoes up tight to the drums? You'll always have to pump the shoes up against the drums if you haven't. If you have, then I would also suspect the master cylinder except that, if it's bad, the pedel would fade to the floor while holding the brake on. If it doesn't do that then it's got to be the shoes needing adjustment. Here's how in case you don't know. Keep in mind that you are turning a cam that takes very little movement to adjust.

Keep us informed of your progress.

The technique when manual bleeding can sometimes be the problem. You want to slowly and fully stroke (not pump) the pedal while bleeding each cylinder. It's best to use a 3' or so length of Tygon tubing pushed over the bleeder, coiled up slightly higher than the cylinder, and then empting into a container. This allows a good visual of the flow of fluid and air coming out of the bleeder. The bleeder should only be opened enough to have a slow steady flow, and then shut when the pedal bottoms out. (This requires good communication between the bleeder and pedal pusher )

When some pressure can be developed, do a leak check by applying high pedal force. If the pedal remains solid and does not move to the floor, and there are NO leaks or weeps, repeat the bleeding process two or three more times per wheel until only clear fluid comes out of each bleeder. Make sure to check the master fluid level often.

A good bleed will not overcome shoes that are shot or out of adjustment, so make sure the brakes are within spec before attempting to bleed the system.
