The brake booster can not cause loss of brake pedal. The steel linkage is continuous from the brake pedal, thru the booster and to the master cylinder. The booster acts as a "helping hand" to increase linkage "push" pressure into the master cylinder and thereby increase hydraulic system pressure to the brake calipers. If the pedal is high and hard with the engine off and drops with the engine running, then it sounds like the booster is OK.
For some reason the calipers are displacing more fluid than the master cylinder is storing in it's cylinder. When you crank the engine and the pedal travels almost to the floor, can you pump the pedal once and gain any additional pedal?

I know that I asked this before, but are you SURE that you have the correct calipers on the front? From all that I've read and scratched my head about over this saga, I sounds to me that the problem lies there.
