Ok, need some ideas. Replaced the whole brake system, Drums around. tried to vacuum bleed the lines initially and then we both got on it by bleeding it the traditional way. I've put over a quart through it now, I don't see any air in the fluid as we bleed it .
It does have brakes, it doesn't lock up and the pedal goes al the way to the floor .

I'm presuming I should have full brake at 50% pedal

Is there just air stuck in there somewhere?
If so, how do I get it out?

Drums around, power brakes, new everything
