What are surge brakes?
Most hydraulic trailer brakes operate on the surge principle. The coupler assembly is known as the actuator and contains a master brake cylinder similar to that in an automobile. When the brakes are applied in the tow vehicle, the trailer “surges” against the tow ball forcing fluid through the trailer hydraulic system actuating the brakes.
