If your van does not have a break-safe and there wasn't one previously fitted I would give very serious consideration to not fitting one, as there are issues where those of us who have vans that came with a break-safe system are now required to have a battery monitoring device fitted, to ensure that the battery that operates the break-safe is not flat. and is capable of applying the van brakes for the specified time.
If you still want to go ahead have a chat with a dealer who sells your brand of van and they could refer you to someone who could install one for you.

Hope this helps

That $950 quote seems extreme to me too. My JAYCO came fitted with this system www.caravansplus.com.au/catalog/product_info.php. I reckon it could be fitted by a competent DIYer. I would recommend that if you have solar panel(s) and a house battery then power it off the house battery instead of the 7amphour battery and you should never have to worry about the battery going flat.

Thanks Aussie but the law states anything over 2 tonne must have the breaksafe and in NSW must have a battery monitor.
Thanks Bald Ed, yes I bought a unit today for $300 and will have a go at fitting it myself

How did the van pass a roadworthy with no breakaway fitted ?

Obviously van is purchased in Victoria, registered as a trailer thus no roadworthy needed.

Hi Bill
If I had been the original buyer I would definitely have put it back on the manufacturer {Golf } to fit it, but as I am the second owner I would have no chance, thought maybe the law was passed since 2015, when the van was built, I'll sort it out

The regulation regarding break-safe units goes back to last century.

They easy to fit. 3 wires tied in to van battery.

I Paid $64 del for basic unit off ebay.
Aussie dealer.

40 mins to fit, incl a coffee\Biscuit.
