It will depend on which size hubs are installed.

If you remove a wheel you should be able to see the make and size cast on the hub somewhere....or measure the diameter and depth.

Possible options, if they are Knott brakes, are likely to be:
160*35
200*50
203*40 (this is what is on my 3.5)
250*40

If you can work out the hub then this page shows you the bearings used, however, better pricing can be achieved than shown here elsewhere:

If you can leave it all dismantled then the bearings themselves will have the part number on them for definitive identification.

just to give a little help on saveing a few quid i have been doing a refurb on a 20ft low loader trailer this week, knott 250.40 brake shoes were about 60 quid per axle we got both axle sets relined for 48 quid, bearings were ok, just washed out with diesel and repacked with fresh grease, new split pins and all is ok,
our local bearing suppliers are bearing man limited, bml or goldline bearings, i did have to buy an 8ft piece of 4x2 5mm steel channel for the chassis and make up a new rail, that added 40 to the job but still less than 150 including 2 new tyres

Wheels wont spin freely

Did the job myself in the end, not without a few hitches, brake adjusters seized up etc

Finally got everything back but I am concerned that the wheels will not spin freely. I guess the new brake shoes I fitted stand a bit proud of the old ones but even with the adjusters fully closed the hubs rub on the shoes and although we can move the trailer, I would have thought there should have been clearance?? Is it OK to just expect these to wear down after a few miles, strangely the trailer rolls backwards fine, its going forward the rubbing starts.

Also I replaced the bearings, the ones provided by Trailertek (who really seem to know what they are doing) were not the same as the ones I took out. Those removed were fitted flush on the inside whereas with those I have now fitted (and hammerred home) there is a 1/16th inch gap all round the rim, is that just a different fitting on a different make of bearing (they were also a lot cheaper than those sold by Indespension).

Grateful for any advice please?

Forgive me for asking the obvious, but did you fit the shoes the right way around?

The auto reverse mechanism only works one way.

I fitted them on the same as I took them of, but in all honesty that one crossed my mind. How would I know? There is no handbook, the seatings into the handbrake mechanism at the bottom and the brake adjuster at top appearred to fit well so I assumed it was OK.

Maybe I should try turning the front shoe which moves the other way up and see if that helps?

I took the hub to BRT bearings in Portsmoth
they checked the numbers and new bearing 17.50 each
going slighty off tack
why do we have to have Brake shoes
why not brake pads like the Americans do
it seam that in most case its the brake shoes that swell and rub the drum
the heat melts the bearing and we all know what happens next
cant find any law thats says drums only
Is it cost at the point of sale ?
