Surge brakes use trailer inertia to apply hydraulic brakes. Electric brakes use a controller in the tow vehicle. Pick the system your trailer already has, then maintain it properly.

A surge actuator on the tongue pushes fluid when the tow vehicle slows. They need no brake controller, but they behave differently in reverse and need actuator care.
Electric brakes need a controller, a seven-way plug, and a breakaway kit. Gain and boost settings matter. Match shoes, magnets, and controller habits to the trailer weight.
