Brake problem, badly need suggestions

[Matt Colie]

Tom,

It sure looks like you have covered everything, and I have never done any work on a Hydroboost. What I can imagine is that the servo valve in the
booster is not set up properly, not unlike when the pushrod in a sensitized booster is the wrong length. I say all this, but I do not know how to
check or change it with a Hydroboost. I can tell you that I had to help out a sensitized booster install that had almost no brakes at all.

I hope some that knows more comes along soon.

Matt

Tom W.:
I concur w/ J R - call Bob Stone - He is the Hydro boost expert and a good guy - just give him time to understand what all you have done and then to explain his thoughts!
Mike/The Corvair a holic
P S - I have his phone number if you need it!
