Re: Which Brake Booster/Master Set Up???
Steptoe, I understand what your saying about your being able to drive with a low vacuum power assisted brake car. Your obviously a true Hot Rodder like myself. Personally, in the past I have a tendency to accept nuances in my personal vehicles that would not be acceptable to the masses. But for me often times in the past in exchange for one thing I would sacrifice another. But it is not good general advice to tell others to do what I have done. This is a true "Do as I say, not as I do scenario".
And the thing is now we have some many solutions to have your cake and eat it to as it refers to activating the brakes with the availability of awesome manual master that almost feel power assisted or Hydroboost if someone has low vacuum they can still have great power brake performance and feel.
The problem with low vacuum power brakes is:
The car will make vacuum at cruise, you let off the gas to slow down and hit the brakes, not problem, Good power brake pedal, feels right
lift off the brakes slightly (car is idling down) and re hit them like we commonly do approaching a stop light, sign, turn, and the second hit of the brake, hard pedal, Slight sinking feeling in stomach
lift again a bit and the 3rd hit of the brakes, REALLY hard pedal, Balls are now in your stomach! LOL!
You and I have both dealt with this and looked it over. The OP does not have to do this.
I am betting the OP has plenty of vacuum as it sounds like he has a mild small block. If not, there are manual master cylinder solutions for consistant brakes.
