  • Tandem master cylinder piston protection with centering guide
    Patent number: 5964140
    Abstract: A master cylinder for attachment with a pre-installed brake booster includes a housing having a bore to receive a piston and piston rod. An outermost end of the piston rod has a guide member in the shape of a funnel which centrally aligns a push rod in the brake booster with a blind bore in the piston rod during attachment with the booster. In addition, a sealing boot is provided on the master cylinder to protect the piston rod outer sealing surface from foreign material and foreign objects that would otherwise contact the piston rod surface during shipping, storage, and installation. The sealing boot is attached at one end to the housing and at an opposite end to the guide member.
