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:
This Kelsey-Hayes combination brake valve was removed from a 1995 Chevrolet Caprice. According to my parts catalog the original applications include 1994, 1995, and 1996 GM B-bodies (Buick Roadmaster, Chevrolet Caprice, and Chevrolet Impala SS) and 1993 - 1996 GM D-bodies (Cadillac Fleetwood Brougham) with anti-lock brakes. The original GM part number for this valve is 10223533; that number is stamped on the body of the valve. The ACDelco part number is 172-2104.
