Need Hydraulic Pressure Accumulator for Coupe Q

[Ben Swann]

Any off the shelf suppliers for a Bomb to fit '90 Coupe Quattro?  It should be same as
the 200 Q.  I know Dave Kayes recharged them, but need one sooner than that.

On that note,  I have problem/symptoms are rock hard pedal which persists even after car
is started and running.  Was working fine and then the brake light went on - goes on
with pedal pressure.  After that I did not get pressure.  Power steering is fine.
Brakes work fine, but no assist.

Check Valve?  How to check that?

I'm content to simply outright replace the bomb since it is original, but if this is
something else, certainly don't want to waste my time and money.
