Wilwood Brake Problems!

[Tom 72RS/SS]

Well, I don't have good news. I removed the cover from the mc and one hole was plugged. Then pulled out fluid to about half full or less, reassemble and off I went. Within 30 min. I could feel the pedal getting firmer but this time the noise seemed to be mostly coming from the rear brakes and at slow roll, coasting to a stop, it wouldn't roll on it's own. Needless to say, the brakes were heating up again and making that noise again. I tried adjusting the prop. valve but no significant change.
Drove home and jacked up the left front and it was hard to turn. Popped the bleeder valve open for a second and it was better (not free wheeling) but better. Did the same for the left rear with similar results.
I bought the Wilwood mc, chrome 11" booster and prop. valve from CPP as a package. The master is 1 1/8 bore which correct for that size booster so unless something is faulty I'm really at a loss here. The only thing I haven't tried is shimming the master away from the booster to see if there is any change. What do you guys think?
