    Got a Suzuki VanVan, previously owned by a gorilla, and the steel liner in the rear brake drum has come adrift

    I've been looking on fleabay for ages, and replacement wheels are thin pickings - either look like they've been dragged out of the canal, or are very pricey.

    Wondered if it were possible to have a new liner sweated into the hub?

    The drum brakes I’ve seen appear to have the alloy hub cast around the iron band.

    A decent machine shop could do that for you, might not be cheap though. I'd say get a decent secondhand one, even if it does seem pricey. Probably easier and cheaper than repairing it.

    Second hand and not scrap you're looking at over 200 plus carriage, and the wheels are crap at best, so most have the spoke nipples virtually rusted to nothing.

    My wheel is OK otherwise, so thought better the Devil you know..

    You might like to compare the brake hub with the ones fitted to the GN/GS 125 family, looks very similar and Suzuki are renowned for having the part sharing ethos down to a fine art.

    Might be worth asking qRhayader precision eng. if he could peg it back in..01597811056

    Sadly the lining has broken up - all that’s left is a thin section which is split also.

    Poor job.

    The "liner" is more likely to be cast iron than steel. And rather than "sweated" in it would generally be shrunk. I don't know where you're going to find someone to cast you a new one and if you could it'll be horrifically expensive - then you've got the machining and shrinking in. It would probably cost more than the bike is worth.

    Far better to find something dimensionally similar and adapt it. As 1913 says it is likely that something very similar is fitted to another Suzuki model.

    As Ian said, it's not a simple process. If you consider machine shop time at 50 an hour (which is conservative) you only get 4 hours for your 200 and then there's the cost of material on top.

    If you can find one where the hub is decent you can get the rim relaced.

    There's a reasonable one on eBay ATM for 139 BTW.

    check the suzuki part no and see if another hub is the same and get the wheel re-laced?
