Jason, there is a really good diagram of the prop valve on gnttype. Check it out. Just wedge something in front of the prop valve and the lower control arm; it'll push the plunger in. It's very small; you'll see what I mean. As for bleeding the master cylinder, just remove the brake lines from the master cylinder, put a rag in front of the holes and push the pedal until fluid comes out, then reconnect the lines. Protect your paint from splatter with a big towel, fender cover, etc. It'll eat everything in it's path.
