I'm answering this since you asked about where in PA but PA is one huge state, and you have next to zero in your profile information so where in PA are you located? How about a first name?
I have two shops I'd recommend depending if your somewhere in the area.
With your information given it would seem most difficult to establish what might be wrong. What was determined to be a root cause for each issue? Or was what you wrote the fix to just add parts? Not meant as a negative comment but I'd want to take an issue like "brakes" to a mechanic (shop) that know brakes and can determine what went wrong and what to fix and not necessarily to an engine builder and then a fellow racer also a mechanic. Why the need for a vacuum pump? You stated the master cylinder went out but did the racer also mechanic determine again root cause. Your car brake system needs a full review and attention of a acknowledged brake expert. Good luck!
you are exactly right when you say i need a shop that knows brakes that is why i am asking for recommendations never found a root cause because everything they did fixed it temporarily vacuum pump was because i was right on the edge of my motor making enough vacuum running a near 500 horse 383 stroker i live in clearfield pa but own a truck and trailer and am willing to tow far to get this fixed my name is Eric and thanks for the help.
