Need Hydraulic Pressure Accumulator for Coupe Q

[Huw Powell]

Ben,

 From what I've read here, don't go messing with the bomb until you can 
verify that it is bad.  Get the brakes working properly first.  The bomb 
has nothing to do with the brake assist when the engine is running.

Sounds to me like you might need to do a superflush of the PS/PB fluid 
system.
