Brake Booser or Servo Issues??

I don't know whether the issue is the booster, the bomb or the ABS system,
but bomb replacement on the 200q20v is about as bad as Audi has made it.
The bomb is anchored with a bracket that has two bolts that are very
difficult to get tools/hands on.  Disconnecting the line to the booster is
complicated because there's little room to put a holding tool on the bomb
and a wrench on the nut.  And there's not much room for disconnecting the
hose from the pump.  I replaced mine using a hoist and I just can't imagine
doing it while lying on your back with the car on jackstands.
