    Those previous owners are awful people, I bought all 5 of my Trumpies new, first one in '94, last one in '16, so haven't suffered those butchering rascals.

    The torque figure at 18Nm is, imo, a bit much for those soft pins, I give the pin a lick of brake grease with copper grease on the thread, then just nip them up with a short alan key, checked that, it's about half, eg 8 or 9Nm. Never had one get stuck so never had to replace any.......yet.

    After wrecking the socket heads getting them out, I replaced my rear brake pins with a DLC (diamond like coating, IIRC) stainless pins from Pro-Bolt.
    No idea if they're any better, but last time I needed to take them out they were fine, but then that's not too unusual!

    Bad bit about oem pins is, they're a tad soft, good bit is, they're soft enough to drill out if the hex gets chewed up.

    Mine had only done a couple of thousand miles from new so I was thinking I'd check they're undo-able before they're not.
    I got away with forcing a torx bit into the hex, needed to take the calliper off though, so made a 10 minute job into a couple of days wait for the new pins to arrive.

    Galvanic reaction between two different metals is a real thing.  Steel pins in an aluminum casting is just sticky business.  I plan on using anti-seize grease on the replacement pins when installed.

    The Sprint is much better in as much as the calliper was on top of the disc, so out of the way.
    I've always wondered if the Sprint set up can be fitted to the SSSA Tiger.
