Today I just noticed that one of the bolts that hold the caliper to the rear hub carrier had the threads damaged. Since there are two identical ones, I couldn't tell at first which heli-coil was responsible. So I ended up using a tap to chase the threads on both heli-coils. Barely any metal was removed. It is quite a job getting a tap in there. After reading about how Toby says that cut threads are not as strong as rolled threads, I figure that a heli-coil must be even worse. In light of this, I didn't re-thread the damaged bolt. I got another one from a junker. I'm not asking a question with this post, really. I'm just saying that chasing the thread on a hub carrier heli-coil was needed and has been done. Does anyone think this is a bad thing to do?
