Dash Air Valve


Recommended Posts

RandyA had a recent excellent discussion on replacing his dash air valve. Have noticed when I push in my yellow parking brake release knob there is not a quick "whoosh" of air but rather an application over 10 - 15 seconds. Pulling out the knob has the typical "whoosh" and the brakes are set. The brakes do release completely but just more slowly than previously. Ideas? Or just replace or rebuild with the kit?

Mine was doing that for about a year before the seal(s) finally blew. If I pressed or pulled hard on either valve when in its "set point" I would produce leakage. New one is working like a champ with no issues.



You were right. Mine is a different part number than yours 85123221. Couldn't find a rebuild kit for that number yet. New valve is low of $334.
