A railroad freight car brake beam strut assembly including an elongated strut having first and second joined walls. Each wall of the strut defines a bore opening to a hollow center portion and to an exterior of the strut. The bores defined by the walls on the strut accommodate a brake lever pivot pin extending through strut thereby connecting the brake lever to the strut and so as to allow pivoting of the brake lever. Each bore defined by the walls of the strut has a closed marginal edge. One brake pin bushing is accommodated in each bore defined by the strut so as to journal a lengthwise portion of the brake lever pivot pin. The closed marginal edge of each strut bore arranged in juxtaposed relation relative to the end of the brake pin bushing disposed a farthest distance from the axis of the strut defines a plurality of radially spaced stops formed as an integral part of the strut for inhibiting inadvertent axial displacement of the bushings away from the longitudinal axis of and relative to the strut thereby fixing the pivot axis of said brake lever relative to the strut. A method of manufacturing a railroad freight car brake beam strut assembly is also disclosed.
