Thanks John. I haven't looked at this system in years. Wilkinson's site identifies it also. My internal booster diaphram may have died I think? Funny how you can't hear a leak hissing in it though? Not much to complain about since it is the original.
Just goes to prove to me that you don't really need power assist on these brakes at all. Always wondered why they put them in the car at all?
I don't get why it has to be a 5/8" hose either. That doesn't help the idle quality. That's a huge drop in engine vacuum. works best with the stock cam. Not the monster that I'm running.
