Well we bled the brakes again, and again had the same results. Then we started to look at the proportioning valve. I redid the brakes about 2 years ago and we figured out that I plumbed the lines from the MC wrong. I had the small reservoir going to the front brakes and the large reservoir going to the rear brakes.:doh: After that We changed out the prop. valve with one that Chuck had on his parts shelf and we ran the lines correctly. We bled the brakes again and got good flow out all the lines. The I took it for a test drive and the brakes seemed a lot better. They are still a little soft and touchy at the bottom of the peddle but a big improvement from the night before. I've adjusted the push rod from the booster another 1/2 turn and it didn't seem to make a deference. After making the prop valve swap and correcting the lines we never did check for vacuum to the booster.
I think I may just keep adjusting the rod until I can find some type of change in the feel of the peddle. I'll start by taking it all the WAY back to the shortest measurement so that the rod is barley engaging the MC (giving me pressure to the brakes) and still allowing the MC piston to retract (releasing the brakes).
