Trailers equipped with a Hydraulic Surge Brake Actuator system function by a surge or push of the trailer forward. As the towing vehicles operator applies the vehicle's brakes the centrifugal force causes the trailer to push forward. When the trailer pushes forward, the hydraulic brake actuator slides together and the master cylinder is applied to engage the brakes.
