    Actually, Powerline's 48 was on the right track, as it is a one piece plastic cast chain. The trouble with that one is that it was straight, indicating that the hand brake was permanently ON. Had they made the casting with a slight curve in it, it would have been quite suitable.

    The staple idea has merit....IF you could manage to get a tight enough loop bent where it joins on to the end of the chain.....the tolerances are VERY fine indeed and I think even the smallest staple available or even a piece of 0.4mm brass/copper wire would be too large!!! Maybe a strand of fine copper wire stripped from a "household appliance" cable would be fine enough, but still difficult to work with.

    If brass wire that fine would be too fine, then the chain itself must be the finest that we have seen from any manufacturer, I think the finest chain that is usually available is around 40 links.

    Just reread your post saying the chain came off on the brake cylinder end, could you remove the D shackle from the piston rod, & make fit wire through there & into the chain, is the chain metal or plastic, if metal maybe solder hard wire to the chain & drop the wire through brake arm, if plastic do the same but use super glue.
