George, my prop valve is from Master Power Brakes, and it is outstanding. It stops great, and I don't believe I've ever locked up a wheel. It is really a combination, proportioning/residual valve. I have front disc brakes. Call them and ask them for a catalog. It has a wealth of knowledge about brakes and how they work, especially pertaining to the various prop valves.
