Many boat trailers havet surge brakes.
Many boat trailers keep brake systems. Boat brake systems are either electric brakes actuated by a switch in the tow vehicle brake pedal, or hydraulic surge brakes.

These brakes are quite elementary and can be repaired by the boat owner using tools available in most internal workshops and supplies purchased in boat marinas or Car parts stores.
