Did a quick search and couldn't find anything, so here goes.
I changed out my brakes and one rotor today. When taking the rear caliper bracket off to change the rotor, I had to break the two bolts counter clockwise like usual, but had to remove them by turning them clockwise. Okay, I thought, whatever. Installed the new rotor and went to reinstall the bolts, but they refused to thread back in. I assumed the bolts may need to be replaced. Quick trip out to grab 2 new bracket bolts and the bottom one threaded in fine, but the top bolt went all the way in, got semi tight, and loosened back up. So obviously there is shaking in the caliper if I attemp to drive it.
So what are my options here? Thread locker, new bracket? I have no idea.
