|trailer breakaway brakes|
I am writing this to try and simply explain to owners of heavy boats which trailers need break away brakes in Australia.
I believe this is needed because many trailer repairers, manufacturers and owners do not understand the law on this sensitive issue and appear to be opting for expensive complicated braking systems when simple over-ride brakes are perfectly legal and adequate.
The Australian design rules require breakaway brakes when the trailer axle load exceeds 2000kg. The drawbar load in not included in this weight and typically would be an additional 150-200kg capacity for a properly rated trailer.
Trailers with an aggregate trailer mass of 2200kg can legally use over-ride brakes providing the axle weight is less than 2000kg.
Manufacturers that are limiting the aggregate trailer mass to the axle load are derating the trailer needlessly and if they tell you that you must buy breakaway brakes when your axle load is less than 2000kg, they are wrong and probably breaking the trade practices act.
Beware of ignorant experts and of course the registration authorities.
