Rebelistic Posted October 23, 2006 Report Share Posted October 23, 2006 I recently lost a bolt in my hope caliper (mono or mini I think, not too sure), but when I tried to replace it I found that the thread in the caliper had stripped. The thread for the other bolt has also been stripped and replaced with a bolt and nut to hold it together in the past and that works ok.The problem is that there is less space for a nut on this bolt hole as it is thicker and so a nut will probably foul on the rotor.I either need a bolt that is just the right length with a very thin nut (so it won't foul the rotor) or I need to get it re-threaded if that is possible. Or I need a new break.I hope this makes sense Does any one have any suggestions?Cheers Quote Link to comment Share on other sites More sharing options...
mat hudson Posted October 23, 2006 Report Share Posted October 23, 2006 you could get it helicoiled, most engineering firms will do this for you. Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted October 23, 2006 Report Share Posted October 23, 2006 Nut+Bolt. Then file it down?Tap the thread, or helicoil it. (as said above)The thing with helicoils..( I think) is that it can only be done if the thread ends. Not like a threaded hole. if you get me?The inserts stop at the bottom of the thread, then you knock the bottom bit out, and it stays in place.Unless there's a way to do it in a 'hole'.

RobinJI Posted October 23, 2006 Report Share Posted October 23, 2006 Yeah, helicoiling's when they tap it out to a bigger size, then put in a steel insert to bring it back to the same size, which will be an M6 thread in your case. If it is an older hope mini, the silver ones rather than a new Mono, then you could just replace the caliper half. Quote Link to comment Share on other sites More sharing options...

Thanks for the link that looks like my best bet, I didn't know you could get that half seperately.Thanks for your help Quote Link to comment Share on other sites More sharing options...
