A proportional or inertia-based brake controller uses an electrical circuit called an accelerometer to sense changes in momentum. When the driver presses the brake pedal, the brake controller applies power to the trailer brakes in proportion to the vehicle’s momentum.

How does integrated trailer brake controller work?

Consisting of a battery mounted on the trailer and a cable connecting the trailer to the vehicle, the breakaway system is activated if the trailer breaks free, pulling the cable out of its plug with it. A switch will then trigger the battery and apply the trailer brakes to slow the trailer down.
