The top fork post mount threads material has disintegrated on the inside from tightening and loosening caliper bolts over time (14 months) on my 09' Lyrik fork. This doesn't allow for tightening down the caliper and/or adaptor bolt adequately, thus causing the caliper to be a smidge loose on that side and messes up the rotor alignment whenever riding. Is there a fix for this without having to "helo-coil" the threads? JB weld with new bolts? Or am I looking at new lowers altogether? I have already tried using a longer bolt with washers to bite some, but that didnt' last.

Thanks.

Heli-coiling would be the best permanent solution. I don't know that I'd trust JB Weld on something as critical as a brake.

Heli-coil is the best option. It creates a thread much harder and stronger than the original.

But check your bolts too. Every stripped fork thread I've seen came from a dodgey/damaged bolt thread.

Have your shop contact SRAM for you...SRAM has excellent customer service. Since I am sure you torqued to spec using a wrench, then it would have to have been a faulty peice of mfg, and isn't the first failure I've seen at that point.
