Ok,
Tested check valve and it was fine.............so, I thought, I can test the
line all the way to the booster by taking it off the booster, and plugging
the end................No leaks there..........the gauge help
solid...............Now where the tube pushes back into the booster is a
grommet that fits tight.  No leak there.  now when I step on the brakes,
they go straight to 0 on the vacuum gauge.

I want to be sure before I swap the booster............This booster was a 2
year old rebuild.  Should the vacuum stay the same when the brakes are
applied, or maybe even increase?  Or, when you step on the brake, does the
pressure release somewhere?

I have to go on about a 600 mile trip on Saturday, so I want to tackle it
tomorrow if i need to swap out..........
