Doc....congrats on passing the big tests!! :thumbsup: It looks like you converted to a modern 2 bolt master cylinder in one of the pics a few pages back. Is it possible that the plumbing between the master and the prop valve could be reversed? If it is, that may explain the brakes sticking if the front brakes are plumbed to the drum/rear portion of the master. I had a sneaky idea on the driveway oil spots! If the stains don't come off, pry the stained pavers out and flip them over. :) That should just be sand between them. You may have to go all Ninja to do it without getting caught, and do it at 2 am under a tarp so the HOA biddies won't see you....lol.
