This document describes how to rebuild the 1970 - 1971 Mopar 3466156 and 3466157 brass metering/hold-off brake valves manufactured by Kelsey-Hayes using a new seal kit available from Muscle Car Research LLC. The same basic part was also used on 1968 - 1969 full-sized Ford police cars and taxis (part number C7VY-2B161-B), 1970 - 1971 Ford Galaxies and Thunderbirds (part number D0AZ-2B161-B) and 1968 - 1972 Ford F250 and F350 trucks (part number C8TZ-2B161-A). Tools needed:
When faced with a leaking brake valve, many adventurous home mechanics follow the same path I did and wonder if it's possible to rebuild the valve. Many valves can indeed be rebuilt, but it's important to understand that it can't usually be done using seals found at your local parts store. That's because the Nitrile/Buna-N or Viton (a fluoroelastomer) rubber compounds used in o-rings and other seals found in "over the counter" kits aren't compatible with automotive brake fluid - they're designed to be compatible with petroleum-based fluids like engine oil and gasoline!
