Weirdest **** ever !

So I was driving home and I went to apply my brakes for an upcoming stop sign, a normal amount of pressure applied, I heard a huge clunk and my first thought was my axel was snapped because the noise was occurring with tire rotation, so I checked my axel and it was fun on both side (still at the stop sign, no one was around thank god) and I assumed my brakes locked up, so I was slowly driving home and whenever I touched my brakes the worst noise and vibration came from my front driver side wheel, pulled in my driveway and jacked it up, only to find that my brake caliper bolt had completely disappeared and the noise was my caliper rubbing on my rotor !!!! It's a 3 dollar bolt, and it's a good chance to reprint my calipers anyway, but how did this happen !?!?

REpaint means you painted them in the past, right? And how did you reattach them? Did you use a torque wrench and take them to correct torque? (81ft/lbs) That's a lot more than "goodntight". Check the other ones....I'll betcha they aren't anywhere near tight enough, either.

Short version: you didn't get the bolts tight enough. You were extremely lucky.

I'd recommend using some thread-lock on those bolts.

looked at the pic wrong.....

i mistook the caliper retaining pin for the carrier bolt. locktite on the carrier bolt has been used by some, gm in particular, so it's not uncommon to see it used.

however, i always like to follow torque specs and make sure the threads are nice and clean.

i hate to torque dirty fasteners...

Thanks for the tips guys, it turns out when I bought the bolt at auto zone a while back since the bolt was stripped by the previous owner, it wasn't the reinforced bolt and literally snapped out! Luckily enough I only replaced one bolt and not the others !
