Rear brakes bolt won’t tighten on bottom of caliper
1 Answer
If the bolt threads will not engage in the caliper hole one of the two are stripped/damaged. If you can inspect them and determine which is bad, then do so. If not try a different bolt in the hole and see if it grabs. Still not working, replace the caliper or re-tap the bolt hole. Oh, and make sure you are using the correct bolt. It may be longer/shorter than the top one.
