Man, I've got so much stuff out there I don't even know where it all is! But if it helps at all, I can tell you that VWs (and probably other master cylinders) have a problem when you set up the brake push rod so that there is zero play in it. The end result is that the brakes will lock up after braking a little, due to expansion of the fluid, or even sitting out in the sun as the temps rise. Probably not your problem, it sounds like, but another data point for the investigation. Now, fast forward to John Martindale's comments made later (I'm reading two days of email in one sitting)..."Now apply a relief port towards the end of the master that normally allows fluid to spill around the smaller plunger and return to the resevoir in the event of heat to overcome the above scenario. What if the plunger doesn't return sufficiently to uncover the port because of the pedal weight. Bingo, lock up again." Now I'm really thinking this might be it...
