The thread in one of the (post) disc mounts is now bare. When they came my way a bit of loctite would keep things in place but a couple of screwings/unscrewings and the thread is no more and not even loctite can save the day.
Is there anything i can do to save them? Bear in mind that I'm on a budget and that the cost of replacing/fitting the lowers would probably be close to what I'd spend on replacing them (second hand, natch). Oh! And I don't have any heavy engineering tools to hand.
So, are they, to all intents and purposes, done for?
