$750 is waaaaay too much. As far as I know, rebuilt racks with core
exchange run for about $250 in US. Check

When does it happen? There's a pressure accumulator (aka "the bomb") in
the system which (if it works, which is a rare occasion on old Audi ;-)
) holds about 0.5 liter of fluid under high pressure. If you discharge
it (which normally requires pumping the brake with engine off, but can
also occur if the has internal leak) this fluid will go back to the
reservoir. If the reservoir is filled to the "max" level with the bomb
charged, there won't be enough space in it to hold the fluid from the

This is most likely a leaking servo.

??? Never heard about it. The pump is the less reliable element of
hydraulic system on these cars, it would rather blow than overpressurize

As one of the listers pointed out, Audis are made using the technology
from the Roswell wreck. Unfortunately, they didn't figure out why the
h*ll did the alien ship crash :-)

Yes, cylinders are easily replaceable
