Abstract
An anti-rotation sleeve for an electric brake system having a shaft received in and movable relative to a passage of a housing includes a body extending along a centerline from a first end to a second end. An inner surface defines a passage for receiving the shaft and pockets extending radially from the passage configured to provide sliding interfaces with tabs on the shaft. Projections provided on an outer surface of the body and extending parallel to the centerline cooperate with the housing to prevent rotation of the sleeve relative to the housing. Each projection is aligned with a normal direction of one of the interfaces.
