Elite Trailer Manufacturing is recalling certain model year 2012 Livestock Gooseneck trailers manufactured November 17, 2011, through January 17, 2012. These vehicles are equipped with Carlisle hydraulic brake actuators. One of the rotating components in the hydraulic brake pump missed a heat treating operation causing the actuator to wear at a higher than normal rate. As a result, the hydraulic pump could fail and result in a loss of braking ability in the trailer.
