When the tow vehicle is in reverse pushes in on the trailer neck which would activate the surge brakes. Inserting a pin in the neck of the trailer prevents this from happening while the driver is backing up. Surge brakes are actuated with centrifugal force.
When a trailer is being towed behind a vehicle and the towing vehicle applies the brakes the trailing vehicle continues to travel forward through centrifugal force relying on the tow vehicle to slow the forward motion. Surge brakes take advantage of this force to operate the trailer brakes. In contrast Surge Brakes are hydraulic and use the trailers natural momentum to actuate the brakes.

When you step on the brake in your tow vehicle and slow down the trailer pushes against the hitch and presses a hydraulic cylinder.
The more you slow down the vehicle the more pressure on the trailer brakes. In a trailer surge brake system the pump is located on the trailer-as part of the hitch assembly. This special sliding hitch assembly is called a surge brake actuator.
It has a master cylinder built into it but instead of using your foot to operate it it uses the weight. Our trailer is from PMI and has a solenoid inside the coupler which when you put the truck in reverse locks out the brakes so you do not have to get out and put the pin in.

Surge brakes or hydraulic trailer brake controllers are self-contained within the trailer and need no electric or hydraulic connections to the car. Its a passive system that acts only once the car has begun to slow down.
The master cylinder compresses forcing brake fluid through the brake lines to the wheel cylinders which then activates. Trailer brakes of a trailer equipped wbrakes in approximate synchronism wbrakes on tow vehicle and developing required braking effort on rearmost wheels at fastest rate.

This engages the master cylinder that creates pressure in the brake lines by the use of fluid and puts pressure on the trailer drums or rotors depending on the trailer.

With electric or electrichydraulic you have to turn down the gain of the controller once your boat is off the trailer or your tires will be skidding. That is the one main disadvantage of both systems.
