Just wondering if anyone can help, what size axle (square) and what size electric brakes
a 1950 KG GVM caravan should have, Thanks in advance.
John

Are we talking single or dual axle
suspension? Vans of that size are made with both.
More important than axle dimension is the type of stubs (and hence bearings) are on the ends.
This site will give you the capacity of each of the components in your
suspension.

Thanks Peter, I have a van with a single 45mm square axle, it has Landcruiser hubs 6 stud and 10 inch brakes. The axle is bent, I was led to believe it should be 50mm with 12 inch brakes.

I just recently upgraded my box trailer from 750kgs to 1000kgs with brakes etc. In doing so I had to look at axles as I had the round 38mm axle and went the 40mm square which is rated at 1000kgs - I looked at the 45mm square and if I recall correctly it is only rated at 1400kgs so if you have that with a 1900kg GVM then it is underrated.
I would go the 50mm square.

Hi
John, Go 50mm Square axle with Parallel bearings as a minimum. Parallel bearings refer to the outer bearing as the same large size as the inner bearing. Bigger outer bearing is rated for higher loads. I recently upgraded my off road trailer to the same as i mentioned above from Alko
Melbourne, the complete axle ready to install. I bought 10" electric brakes but you may need 12" as you mentioned. My complete assembled unit was about $1250. If you buy from ebay or the net you may be buying bits and pieces assembled from parts made in several countries that may not be totally compatible. Hope this helps! regards Michael

John, I also sourced 1/2" diameter high tensile 'U' Bolts to replace the normal mild steel ones that are readily available. 5/8" diameter are available but I had trouble finding them so I went for the smaller 1/2" diameter high tensile ones. Michael

If you look through the site I linked to in my previous you will se you need a 2 tonne braked axle. The axle will be 50 mm square or 56 mm round with 2T stub profile with 2 T bearings and 12" brakes.
Parallel stubs are only good for 1600 kg rating.
Straight braked axle.

Hi Peter, I mentioned that would be the bare minimum! I wasn't sure if it was 1600KG or 1800KG for parallel bearings. It sounds like the unit that
John has is way under rated! Michael

Phone one of the trailer
places, to many experts here!
At least with a trailer place you know you will get the right advice and if wrong someone to fall back on to for help.
