Introduction

All trailers with a total weight of over 750kg require brakes.

For trailers and Caravans with a GTM of up to 2,000kg, the braking system can be either an overrun system or one with electric brakes operated from the driver’s seat.

Remote control of electric brakes via APP is also allowed.

Overrun brakes are not acceptable on trailers over 2,000kg.

Further, the braking system must be such that if the trailer accidentally breaks away (from the towing vehicle), the trailer brakes will apply automatically and remain on for at least 15 minutes.

The brakes must operate on ALL WHEELS (exceptions are trailers that are not over 2 tonnes Aggregate Trailer Mass (ATM) and trailers manufactured before ADR38-04/–. Their service brakes must operate on all wheels on at least one axle).

Installation of the Caravan Trailer Breakaway System

Trailer and caravans equipped with electric brakes, it is necessary to have the following equipment:

  1. A breakaway switch is fitted to a caravan or trailer, and its attachment point is compatible with the towing vehicle.
  2. A battery, either on the trailer or within the caravan, is of sufficient capacity to maintain full braking for at least 15 minutes.
  3. The towing vehicle has an electrical circuit that automatically keeps the trailer battery fully charged. It is also capable of warning the driver if the battery is flat.
  4. One grounded wire to each brake unit) and not via the trailer suspension components, wheel bearings or tow couplings.
  5. Furthermore, a visible label must be attached to the caravan.
  6. Finally, the breakaway lanyard must be adjusted to disable the pin when the chains are at full stretch while connected to the tow vehicle.

Note:

If the towing vehicle is subject to Australian Design Rule 31/– “Hydraulic Brake Systems for Passenger Cars” or Australian Design Rule 35/– “Commercial Vehicle Brake Systems,” it is critical to ensure that the fitment of any control unit will not alter the towing vehicle’s electric brake system.
