Re: Leak from power assist reservoir

[Kneale Brownson <knotnook@traverse.com>]

My '87 5kcstq did the same leaking through the wire passage before I
replaced the brake boost accumulator ("the bomb").   To test the bomb, run
the engine, shut it off and pump the brake pedal repeatedly.  A good bomb
should give you upwards of 20 pumps before the pedal suddenly becomes very
hard.  Mine went hard after one pump.  The car's brakes worked fine while
the engine ran.
