Engine off, or vacuum line disconnected, a hard pedal is normal. You won't have the vacuum to assist.
If the pedal goes to the floor it's a base brake system problem, like air in the lines, brakes out of adjustment, leaking wheel cylinder or caliper, or a bad master cylinder leaking internally. If you installed the master cylinder without fully bleeding it the first time you have a lot of air in the lines.
Drum brakes, not adjusted properly, will give you a low pedal.
I don't believe you have ANY problem with your power booster.

Ok......replaced bad caliper and installed new pads....re-bled system back to front. Still pedal goes to floor? I'm guessing booster now? At $100 for new I'm off to junk yard tomorrow as they are only $20

Think about how the system works. The booster has no connection to the hydraulics, it just helps you push the pedal down.
You can not compress a liquid, no matter how hard you press. If it goes to the floor slowly, it's a leak, internal or external. If it's just low the drum brakes are not adjusted properly.
Good luck.
