      How does an overrun brake work on a Trailer?

      An overrun brake causes trailers to brake when they overtake the towing vehicle. This happens when the towing vehicle descends and/or brakes. The moment the trailer runs in on the towing vehicle, force is applied to the overrun brake.

      The first pressure is absorbed by the Overrun brake damper, which ensures that your trailer brakes evenly. Next, the draw tube is pushed backwards by the braking effect, by means of a transfer lever this pushing force is converted into a pulling force, which attracts the brake cables via the brake rod/brake assembly. Finally, the brake cables transfer the tractive force to the wheel brakes.

      Knott overrun brakes are also equipped with handbrakes, which are used to park trailers and to brake the trailer when it slips away from the towing vehicle. Trailers with overrun brakes should have Breakaway cables fitted. The moment the trailer detaches from the towing vehicle, the breakaway cable pulls on the handbrake, bringing the trailer to a stop, then the cable breaks.
