Brake booster shuttle valve piston for use on Bendix Airpac models M135 and M211 as used on military vehicles and large trucks. This piston is oversized – we bored an original housing to a standard 1″ bore and manufactured this piston to match. Your housing will need to be bored to 1″ in order to use this piston. This part is for use with our piston seal (BRK-0066-1) and clip (BRK-0066-2).
Material: 303 Stainless
