1. An anti-rotation sleeve for an electric brake system having a shaft received in and movable relative to a passage of a housing, comprising:
a body extending along a centerline from a first end to a second end and having an inner surface defining a passage for receiving the shaft and pockets extending radially from the passage configured to provide sliding interfaces with tabs on the shaft; and
projections provided on an outer surface of the body and extending parallel to the centerline for cooperating with the housing to prevent rotation of the sleeve relative to the housing, wherein each projection is aligned with a normal direction of one of the interfaces:
wherein the projections comprise:
first projections diametrically opposed from one another about the centerline; and
second projections diametrically opposed from one another and different from the first projections;
wherein the first projections extend a first length along the sleeve and the second projections extend a second length along the sleeve less than the first length.
