Self Adjusting Brake System for Trailers & Caravans

Optimum automatic adjustment – every time!

Knott has developed and Type Approved a Trailer Brake that automatically adjusts, ensuring that the Brakes are always at their optimal setting.

When fitted to a overrun braked trailer, the benefits include:-

  • The Knott-patented automatic adjusting control system offer consistent and smooth braking action every time
  • All shoes wear equally and consistently: braking is smooth, therefore there is less wear and tear on the towing vehicle and trailer leading to stress on the coupling overrun damper.
  • Likewise, with reversing, poorly adjusted brakes can become a problem, trailers can be shunted and linkages and overrun couplings damaged. With braking performance assured, reversing will become trouble free as the automatic adjustment system simply disengages
  • No need to manually adjust the shoe lining; adjustment happens automatically and instantaneously compensates for for brake shoe lining wear.
  • Trailer inspection and servicing consequently much quicker, checking for lining wear (are replacements required?) but no need to adjust.
  • For hire vehicles, this should increase the service interval and braking performance is not compromised during a reasonable hire period.
  • Should the vehicle and trailer combination ever be the subject of an off road check, the brakes will be properly adjusted and the handbrake working etc.
  • Available as a retrofit kit on Knott 200 x 50 and 250 x 40 (from 2013) brakes and are easily installed.
  • Tested and approved to 71/320/EEC and UNECE R13 on the current Approval
