Stripped threads for the front brake caliper mounts is a common issue on our trucks (see: here here here here here here). It has happened to me, and I'm looking for guidance that I haven't been able to find in any other threads. I'm pretty much settled on the Helicoil approach. My question is: has anyone successfully done this job with the knuckle still mounted on the truck? How about with the rotor still mounted? I'm mostly wondering about the likelihood of drilling a straight hole for the helicoil and not run into the rotor, etc. Others have alluded to doing the job in 15 minutes, but I guess I'm just not that confident in my ability to drill straight enough for tapping without it being on a drill press. Any advice appreciated.
As an aside, my little trick in an emergency is to get a slightly longer 12mm bolt than the standard 38mm. 40mm is about perfect. I found that the extra length was sufficient to bite on the few remaining good, non-stripped threads at the very end. It won't last long, but it could get you home in a pinch.
Thanks!
