Surge braking is accomplished by replacing a trailer's standard tongue copler with
an actuator and adding hydraulic brake assemblies.
The "surge" or "push" of the trailer toward the tow vehicle during deceleration automatically
synchronizes these 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.
