Abstract
An improved brake linkage system for a railway car, especially a hopper car, having an air cylinder actuated to move a cylinder lever. The cylinder lever is directly connected to a floating operating lever by a slack adjuster which can be made substantially shorter, lighter and less expensive than slack adjusters of prior art systems. With respect to the prior art, the present invention permits use of less linkages, shorter linkages and lighter linkages, thus making the overall linkage system lighter, less expensive and more efficient.
