  • Patent number: 4113073
    Abstract: A wheel cylinder body is made from a constant cross section extrusion having a bore forming the working chamber of the wheel cylinder without further finishing of the chamber wall. A block-like step section, formed as part of the extrusion on the outside of the cylinder portion, is drilled and threaded for appropriate inlet and bleeder screw connections, and mounting holes. The inlet and bleeder screw holes intersect the bore so that they do not engage the sealing cups of the wheel cylinder pistons during wheel cylinder operation.
