Trailer brake conversion.

[Richard Smyth]

If converting a trailer on air brakes to hydraulic is there a ram available that will bolt onto where the air brake chambers come out.

Obviously I could get the combined air/hydraulic setup but not looking for this. Asking here as no one I know of supply these down here

The preferred route is to add air to the tractor, or change tractor.

I hear that but that’s not what I asked for. Just seen a video done by I think tractair doing a conversion and the hydraulic rams removed were on a standard air chamber bracket.

Air brakes on a tractor are rare here. Hydraulic trailer brakes almost as rare. For the occasional use this customer needs hydraulic will be fine. It’s not a legal requirement here.

This any good?

What size rams would people use? 25mm or bigger?

I remember the good old days, back in the late 80s when I was carting on the road (aged 16) with a MF135 complete with one working drum brake I had an 8 tonne marston trailer behind me which had its brakes plumbed into a spool valve. If you had to resort to using the trailer brakes, they were of course either off or on, so most of the you just made use of the 1 working drum brake on the whole outfit

look, tell him you have this really good offer of a compressor fitting the tractor, ideal for running various air operated tools and will blow up tyres too.
get that job done first, then later on ask if he still wants the trailer converted

35 mm rams needed to replicate the application forces of an air chamber to achieve the same brake performance.

Is it ex HGV with air suspension also?

Can’t help you over there in the great southern land, but if you were still here I’d say pop into Hunton Legg and have a look see. I’m sure they would come up with something suitable like what @ste has suggested.

I have a set of 4 rams with brackets to bolt on instead of air chambers.

Postage may kill it...

That looks spot on cheers

Ex hgv but still on springs.

Freight probably not too bad. I’ll find out what they want to do as they are just in the process of buying the trailer at the moment. Whatever we do will have to be freighted from Europe as nothing similar is sold here

I might contact them and seee what they have. It will come down to price as I’ve found the air/hydraulic units for £79 so will need to be less than that.
