• a grounding brush including a support and a plurality of conductive fibers disposed at least partially within the support;
• and
• a brush mounting plate secured to the support of the brush, the mounting plate including a radial portion, at least one centering portion extending at least axially from the radial portion, the at least one centering portion being offset radially outwardly with respect to and axially overlapping the support of the brush and having an outer surface defining the outside diameter of the mounting plate, the at least one centering portion being engageable with an inner circumferential surface of the housing bore so as to center the mounting plate, and at least one spacer portion extending obliquely inwardly from an axial end of the at least one centering portion on the side of the centering portion opposite to the radial portion and configured to establish and maintain an axial space between the brush and a bearing or a housing on the axial side of the mounting plate on which the brush is secured.
