PaRtZ Posted December 27, 2008 Report Share Posted December 27, 2008 you cant. Basically.From your poor english, I have no idea what the problem exactly is, but there are only a couple of ways out of a raped thread:Helicoil is (use the search)Drill straight through and use a nut on the other sideChemical metalNote chemical metal isn't particularly strong enough for something like brake mounts. If its the thread on a brake lever though it may be good enough. But if you want an answer, try telling the forum which threads it is that you've knackered. Depending on what it is, it may be cheaper to buy a new part Quote Link to comment Share on other sites More sharing options...

Daniel C Posted December 27, 2008 Report Share Posted December 27, 2008 I did this to mine But i got a tap out of a tap and die set and just ran that throught thew threads a couple of times and it worked perfect. Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted December 27, 2008 Report Share Posted December 27, 2008 Yeah in this case then cleaning the threads out with a tap is easiest option, not always guaranteed to work though. If you cant get hold of the right sized tap, don't bother going out and buying one, when buying a new tpa or buying an upgrade will be cheaper Quote Link to comment Share on other sites More sharing options...
