A caliper bolt backed out on a 2013 Silverado last Thursday and smoked a wheel bearing
Last Thursday I was finishing a brake job on a 2013 Silverado at my shop here in Boise and something went sideways. I torqued the caliper bracket bolts to 129 ft lbs but one had stretched threads and backed out on the test drive, which ate the wheel bearing and warped the rotor. The customer came back with a grinding noise and I ended up eating about $310 in parts to make it right. Now I always chase the threads and use new bolts on every brake job, even if the old ones look fine. Any of you run into stretched caliper bolts on those trucks, and do you replace them every time or just when they look bad?

It's the same deal with pretty much everything that holds something in place over time. Like the u bolts on a trailer axle, they torque fine one year and the next they're just stretched out from doing their job. Or head bolts on an old 22re, you can measure them and they're a hair longer than spec. The bolts don't fail because you did something wrong, they fail because metal gets tired. Idk, maybe it's just me but I stopped trusting my eyes on stuff like that a while back and started trusting new hardware instead. Cheaper than eating a bearing and a comeback.
