Brake Pedal Fade

Hello Everyone!
My wife's '96 2.8 A4Q is having problems.
When I push in the brake I get stopping power, but it fades as if I'm losing the power and going to manual brakes.
Are vacuum boosters a common failure in 96's?
I did notice that with the car off, if I rotated the vacuum line going to the booster, I could hear it bleed. But with my wife pushing the brake pedal in (Car running) I couldn't hear any bleed by at the booster.
Any help would be appreciated,
Andrew

Is it a common problem?
Vacuum seems to store quite well in the booster. Some 18 hours later when I wiggled the vacuum line to the booster, I still heard hissing.
Are these hard to replace? Couldn't find a tech article on it.
Anyone?
TIA

suggests, since it absorbs water. Fairly simple thing to do which could save you a trip and money to the dealer.
Just a thought!

bleed your brakes? i had a sloppy pedal for a little bit after i changed my rotors and pads, i bled the whole system ended up added all new fluid, dot 5. still had a smooshy pedal. did some searching found the check valve that goes to the brake booster was cracked. 42$ for the whole pipe that runs from the intake manifold to the booster through that bulkhead... works great now...hope it helps.
