Trailer Mounted Electronic Brake Controller

Brake controller chassis mounted, or under-dash mounted. Just four wires to connect. Note: Fuse protection to prevent reverse polarity. Electric trailer brake controllers fall into two categories, they are

  • Proportional
  • Non-Proportional.

Chassis-mounted controllers are non-proportional and are mounted under the dash or on the trailer. Proportional controllers like Redarc tow pro, tow pro elite and Tekonsha provide instant trailer braking forces according to the speed of the tow vehicle. Proportional controllers have emergency manual override control.

How does an under-dash or trailer-mounted controller work? The driver activates the controller from his normal seating position when the brakes are activated.

This product is ideal if multiple vehicles tow your trailer with electric brakes.

How to set trailer braking

The knob on the controller must be pre-set according to the trailer’s weight. Most trailers carry the same weight daily—for example, builders’ trailers, car carriers, pop tops, RVs, etc. Multi vehicles can tow trailers with trailer-mounted brake controllers in Queensland and NSW. You no longer need multiple controllers in all cars to tow the same trailer.

We recommend that a licensed repair facility install Controllers.
