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.

What is a surge brake actuator?

Surge Brake Actuator systems work by the “surge” or “push” of the trailer toward the tow vehicle during deceleration which automatically synchronizes the 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,…
