Need Hydraulic Pressure Accumulator for Coupe Q

[Tony Hoffman]

That sounds like servo/pump/blocked line failure to me as well. My V8Q had a
dead bomb (one pump after shutdown, hard pedal) yet always had perfect pedal
while running. If I pumped the pedal a couple of times in quick succession I
could get a hard pedal also, but it would then go back to normal after a
second or so of running. The bomb should only be for after shutdown, if it's
hard while running there are definately other problems.
