I need help. I'm at my wits end and pissed at the world right now. Here's the basics.
I have a 1965 Mustang. Years ago I did the Versy/Grenada full disc swap with a '67 booster and m/c. It worked fairly well since 1994. About a year ago, I decided that it was time to rebuild and upgrade the system, so I got a Scott Drake 4-wheel disc booster and m/c. I got Willwood front discs and Right Stuff rears (complete setup). I also run a vacuum pump and reservoir because the cam isn't even close to stock (409 stroker motor).
I have a good mechanic install it. He's done work for lots of my friends for years, and he's done good work for me. He spent time on it, and our result is, basically, if I stand on the pedal till my fatass 230 pound body is lifted off the seat, SOMETIMES the rears will lock up . . . eventually. The car has like zero stopping power. She'll stop at a stop light, eventually, but it takes a while.
The pedal is soft till a couple of inches off the floor, then it's hard as a brick. We disconnected the booster completely, and the pedal gets harder sooner, BUT the braking is still about the same.
About the only thing I can think of is that the Scott Drake master cylinder isn't putting out any power. I'm going to put a gauge on it Monday and see what I get.
Have any of you guys had issues with this related to any of the components I listed? Any ideas at all? About all I have in mind is that the m/c is bad.
Help?
