Your local service shop sounds highly suspect to me. Check the
archives for the "bomb" test - this sounds like a typical pressure
accumulator failure. If so, don't buy a used one - I lived with one
for 18 months and it never worked right. Try Blaufergnugen for a new
one. Expect to pay $250 +/-.
There are three hoses to the bomb. One is a no-pressure return/drain
line from the reservoir to the bomb. If that's leaking, it's just
plain cut or worn thru, but it will NOT afect pressure. The other
two lines do carry pressure, one is 2200 PSI, the other I don't know
but it's not as high. The pressure hoses are NOT cheap, so make sure
you know what you're doing before swapping parts. Do the tests in
the Bentley or the brake pedal pump-down tests (see archives). I bet
it's the bomb.
