here is the url for the bomb stuff on Scott's site. THe Bomb provides
hyd. pressure for the brake system ( vs a vacuum system on other cars )
this Audi's way of giving you power brakes.
Goto the Bentley on page 47.23 there is a diagram of the brake hyd.
system and on pg 47.24 there is a close up.
I will have to get around to replacing mine one of these days, I get a
brake light on occasion, when stepping on the brake pedal really hard or
turning into the driveway and using the brake.
