To simulate a huge vacuum leak, I just left the vacuum off the booster. Hard to get a bigger leak than that. I still had the same problem, except now without the booster functioning correctly I had to push much harder. Since the behavior was identical with a huge vacuum leak to the booster (well except now I was having a small hernia pushing the brakes), I figured it's not a vacuum leak.
That slowly lowering to the floor part makes me think I have fluid flow. Since it's not leaking out, it's flowing internally. Somehow.
