[V8] The Audi Gods strike again

No previous brake problem.  Since I drive this car infrequently, I am always
amazed at some of the tangible differences between this car and my normal
driver, The Old Gray Mare, a 1990 100 non-quattro.  

But as I have thought more about it since yesterday, I did think that the
brakes were really "soft", although I didn't think in driving it pre-failure
that there was anything really amiss.  In fact, except for the brake pedal
sinking to the floor with vastly diminished braking effect, nothing was
different.  NO warning lights of any kind, no ABS stuttering, no loss of
fluid, NOTHING.  Pumping the brakes makes the car stop.  But the pedal will
just go the floor no matter how much pumping is done.  Seems like a master
cylinder, but if there is a nitrogen bomb, it might be in the final stages
of total failure, too.

I've had more than one nightmare about being in a vehicle and pushing 
the brakes, only to have nothing happen OR the dream car (ha) has only a 
small change in momentum.  Wife says it's about "feeling out of control 
of my life and where it's going."  I say that it's improper maintenance 
of dream cars.

Did the brakes give you trouble ever again?  i.e. on the way to the
