Almost sounds like the brake booster is not doing it's thing. Perhaps the
diaphragm has a hole in it?
When you say you have vacuum there when you pull the hose off, I assume you
mean there is vacuum in the hose. Can you hear air sucking into the booster
through the fitting as well - in other words, is there vacuum built up
inside the booster cavity?
If that's OK, perhaps there is something wrong inside the booster itself. I
don't know exactly how the vacuum is modulated to assist pedal force - there
may be a problem in that. Never had one apart! It's usually one of those "no
user-serviceable parts inside" things. I'm sure they are repairable, but
I've never had one go bad on me.
