Once you understand the basics of how it works, you can start to customize your brake system for the specific needs of your trailer. For those who are new to wiring systems, a 3 Wire Trailer Breakaway Switch Wiring Diagram can be a great starting point. Taking these extra steps will ensure your brake system is reliable and efficient. Be sure to use water-resistant wire and make sure all connections are secure. The switch should be mounted close to the trailer's battery so that it can easily be triggered in an emergency.

The diagram also shows how to install the switch in the right place. It's important to follow the diagram closely and use the right crimp connectors to ensure everything is properly connected. This diagram illustrates how to wire the switch's positive and negative wires to the brakes, battery, and the frame. A 3 Wire Trailer Breakaway Switch Wiring Diagram will show you exactly how to connect the parts of your brake system together. If you're not familiar with how these switches work or how they should be wired, don't worry! We've got you covered. Without them, it's impossible to activate the brakes in an emergency situation. Remote monitors can be purchased separately to suit most existing brake-away systems.Trailer Brake Breakaway Switches are a critical piece of equipment for any trailer.

The monitor is installed near the driver and gives a visual and auditory warning if the battery has low charge, ensuring the system will work if the caravan or trailer separate. Many people still believe they are a good idea to have and most caravan manufacturers would recommend having one. Now the remote monitor is only a recommendation by Transport NSW. Previously (2007 -2016) it was mandatory in NSW to have a remote monitor for the Breakaway System. If the vehicle separates from the caravan the pin is pulled from the switch and the breakaway system will be engaged, applying the electric brakes and brake lights. The switch holds a pin on the end of a cable, which is then connected to the tow vehicle. The breakaway switch is mounted to the A frame. The breakaway control unit, which has its own battery, is fitted to the caravan/trailer. It must be capable of keeping the brakes engaged for at least 15 minutes. A unit is mounted on the trailer and connected to the tow vehicle with a metal cord and in the event of uncoupling in transit, applies the electric brakes to the trailer/caravan. Electric brakes are powered by a brake controller and by law it is required to be fitted within reach of the driver of the tow vehicle.īelow: standard electric coupling, AKS electric coupling, offroad electric couplingĪ breakaway system is a safety device required by law to be fitted to caravan and trailers weighing more than 2000kg and equipped with electric brakes. Most caravans these days have electric brakes fitted as they offer greater control and allow the driver to change the resistance to match the driving conditions. They use the force applied against a slowing tow vehicle through the coupling to apply the brake, the same way pulling the handbrake would.īelow: hydraulic override, mechanical override, offroad override Override brake systems are commonly found on trailers, camper trailers, and older caravans. The GTM is shown on a compliance plate which is usually located on the drawbar.
The minimum brake setup you require is determined by your GTM (Gross Trailer Mass). In this article we will be focusing on brake configuration. While some laws may differ from state to state there are a few standardised nation wide. Knowing your vans limits and legal requirements is not only important so you have an enjoyable holiday, but a safe one.
