I'm tryig to get my Wilwoods buttoned up...

So I have some updated results. As I said before, I removed the residual valve with little help. Well, today I jacked the entire car up (level) and spun the wheels with my hands. The rear wheels spun 1.75-2.5 times before stopping, and the front spun 3-4 times before stopping. Does that sound like the master cylinder is engaged partially? I can't tell.

And so I drove it around the block once more. I did a pretty dang hard stop, and then I removed my foot from the brake. For about three seconds, the car just stayed there, stopped. I even revved the motor a bit with no results, like it was in neutral, but it was in drive. I have no idea what's going on....

More help appreciated.
