Combination valve parts? (brake system)

    Anyone know of a source for combination valve parts, or a rebuild kit?

    This is the combination proportioning/balancing valve with the brake fault switch on it, which hangs on rigid brake lines beneath the master cylinder.

    I need to rebuild mine. I can't seem to find a source for a new or rebuilt valve, nor a rebuild kit or source of some of the special seals.

    In particular, in the proportioning valve part, the piston for each side contacts a rubber seal down inside the bore, that is shaped like a thin rubber washer, textured with bumps, and has shoulder around the outer rim. I can't find anything like this on the web, or in rubber washer kits, or anything of the like. I had to remove the seals in order to clean the valve body thoroughly, but unfortunately between brake fluid and cleaner (used Sea Foam), the seal swelled enough that I can't get it back in place.

    The vehicle itself is a 1993 Shadow ES with a 2.5L non-turbo, with non-ABS brakes, disc front, drum rear.

    It is a discontinued and non-serviceable part. Google for 'Mopar 4485829' and use that part # in your search.
    It was used in non-ABS, frt disc/rear drum 1992-1995 Shadow, Sundance, LeBaron 2-dr/conv and Daytona.
    Ebay, obsolete and NOS parts houses may have one.
