The "plate" where the spring arm hooks onto has split at the exit point and the spring arm has caught under the adjuster screw and stripped the threads. Can't remember the last time I went near those with an allen key so I originally put it down to general wear 'n' tear, but at the same time I might have messed up installing it originally and not realised... Going to send them so photos when I get chance to take a pic in daylight and see what they say...
For now I think I've managed to cobble together enough bits for a second bar/lever/brake/cable combo to save me having to piss around too much to get the bike working again.
Just how did it die? Reckon it worth bothering TRP about warranty?
