A brush holder assembly (12) for a rotating electrical machine such as an alternator (10) has a cavity (56) therein. The cavity (56) is defined by a first wall (60), a second wall (62), a third wall (64), and a fourth wall (66). The cavity (56) is sized to receive a brush (42) of the rotating electrical machine. One of the walls (60), (62), (64), and (66) comprise a first drafted surface. A positioning rib (70) is provided on at least the drafted surface to position the brush (42) substantially parallel to the longitudinal axis (58) of the cavity (56).
