Brad, your ISP doesn't like me, so this is going to the list...
The booster is probably fine. I'd bet on a leak in one of the brake
circuits, or that replacement master went south again. Check all your
fluid lines, maybe have your friend press the pedal while you look for
leaks.
The ABS shouldn't be a cause of this either.
