    I wonder if you can help with some ideas about where I might get a replacement brake drum for my old trailer.

    The bearing seized last year in use and it sheared the centre of the drum off. (Happened in Brightlingsea and miraculously the wheel released at 20mph managed to miss all of the parked cars and was brought to rest by the bumper of an old Transit van! I did’ notice and continued another mile on three wheels before the guy behind got my attention to pull over)

    It is a Watford Axles ‘HBX’ 5 stud 6” PCD drum running R15 wheels.
    I have tried Indespension (who bought Watford in the 90s) and all of the trailer spares places I can think of to no avail. They are all suggesting new axles at the cost of £1500-1800!
    I have also been watching eBay and the like for trailer spares / donor trailers also without luck.

    I bet there is a trailer shop, or a rusting trailer, somewhere in the UK with one of these – any ideas where I might go?

    Those hubs and wheels look very like series landcover ones. The size – R15 is not something I am familiar with. What size tyres are mounted on the wheels?

    The wheel construction (riveted) looks very familiar, as are the 5 studs. Although the hub and brake drum are separate in a landrover.

    So I wonder if a series hub would fit? Otherwise can you get the two parts welded together again? Specialist job, I know, requiring annealing afterwards and it must run true, but cast iron can be welded.

    Getting the wheel bearings off will be difficult but if the broken off part can be recovered then you might be able to get the seized bearings off with a grinder. I have done this in the past with a seized landrover hub. Took all weekend to do though. You might be able to get a stub axle to weld onto the actual axle.

    Trevor, many thanks for the reply.  You have triggered a number of trains of thought, and given me some hope of a way forward.  The first think I am going to do is get the current hubs off and see what I have got in the way of shaft and what else might match the hub. Should have done this before!

    Rather strangely the bearings are completely free. Although something locked up sufficient to break the drum, everything is turning nice and smoothly now.  I can’t remember testing the hub for movement just after the incident but either it froze through heat or possibly it was braking that separated the outer and inner parts of the hub?

    Martin Bennett has also come up with options to get a new drum made up – it might cost a few hundred pounds but is likely to be cheaper than new axles / wheels. He has also know of welding hub faults, although I think this one is a little severe.

    If the bearing is free now it didn’t seize.  Most likely a fault in the casting – or was it welded together during manufacture? If the bearing had seized I don’t think the hub would have broken like that. My experience was of a front wheel bearing welding itself together sufficiently to prevent the wheel turning at 50mph. I was driving in the inside lane on a duel carriage way (the A1) and ended up with that wheel buried up to the axle in the central reservation (which was grass and without a barrier). The empty trailer was blocking the outer lane. Very frightening! Never been so pleased to see a policeman.

    I would take the parts of the hub to a specialist who can weld it properly. Needs heating up evenly as part of the process –  with a furnace/kiln – rather than a welding torch. Then it will need stress relieving, again in a furnace.
