Abstract
A bi-directional over-speed energizing brake system which implements automatically in the event an electric power steering system is in an over-speed condition. For rotational speeds of a rotating component exceeding a predetermined rotational speed threshold, centrifugal force acting on brake arms of a braking assembly overcome biasing by springs such that the brake arms will frictionally engage a non-rotating brake ring to thereby slow the rotational speed of the rotating component.
