Front disc-brake is knackered, the calliper piston is busted (well more the rubber seal appears to have disintigrated so when I went to change the pads the calliper piston itself fell out along with a gush of fluid).
Anyone got a spare kicking around? Happy to remunerate in cash or beer.
Hoping to bag a second hand replacement for the whole lot on Flea-bay later day if I don't get out-bid (but its for the whole front brake system which is a bit of overkill, but would of course leave me with more spares).
