Trailer Parts Superstore® offers hydraulic Disc brake actuators from TIE DOWN ENGINEERING, DEMCO, TITAN / DICO & UFP. Surge Brake Actuator systems work by the "surge" or "push" of the trailer toward the tow vehicle during deceleration which automatically synchronizes the trailer brakes with the tow vehicle brakes. As the trailer pushes against the vehicle, the actuator telescopes together and applies force to its master cylinder, supplying hydraulic pressure to the trailer brakes. When selecting an actuator please consider the towing capacity requirements.
