Well I had upgraded to new rotors last year, without any problems. Then recently i had the rotor off for some work, and put everything back together. A week later one of the Brake Bracket Bolts fell out during driving. If your bottom one falls out, it allows your brake bracket to slide clockwise, and will lock up your tire when going in reverse. If your top one falls out it will slide counter clockwise and lock up your tire when moving forward. If you are moving with any speed when the bolt falls out, it will clean off a nice patch of aluminum on the inside of your wheel.
You MUST put threadlocker on the bolts when replacing them, or buy brand new bolts from GM ($30 per bolt at a dealer, $10 of gmpartsdirect). The GM ones come with threadlocker on the threads.
I was given a general guide to doing the procedure, and was not warned of this before. Also, being a newb at brakes, I had no prior knowledge of this.
Luckily for me, my tire locked up on my street, 2 houses from mine. So I had to let the car sit there for a week, and then on this glorious 25* day (13* windchill) i was in the middle of the street working on my car for 30 minutes.
Enjoy
