IIRC...with the engine off, pump the brakes a few times to use up whatever reserve vacuum there is. Holding the pedal down FIRMLY, start the engine. If the pedal sinks appreciably, the booster is bad.Again this is if I recall the NAPA days correctly. Hope this helps.


I'm 55 now, no time to waste. Not a week goes by that I don't hear about someone passing on.Let's get out there,smoke some tires,have a beer with a good friend,do what you have always wanted to do.I am pretty sure no one will ever say on their deathbed "gee I'm glad my life was calm and boring"
