Mickey, I think your going through the same problem as I am. I have a SAS and the front brakes rotors and calipers were upgraded (I'll have to look at my records to know to what exactly) my rear end felt like it was doing all the stopping and it got so bad that the brake cylinders began to leak. I put in a proportioning valve and the front is doing most the work.

I'm getting the hydro boost bored out and will be switch to the new mc soon, I just replaced the original mc and I still get a spongy brake, happen to me a couple times where it's gone to the floor. Ill gravity bleed tonight to see if that helps
