Did you hear any noises or symptoms leading up to the failure, or was it sudden and catastrophic?
No warning, was sudden and thankfully I was not going fast enough for it to be catastrophic. If this would have happened when I was going faster, I have no doubt it would have been one hell of a wreck.
When I slowed down and was turning into my parking lot, I heard a terrible grinding sound. I replaced the pads and rotors at the end of last year, so I knew the brakes shouldn't be sounding like that.
Pulled into a parking spot and the truck was jumping when trying to stop and the peddle was very soft.
Wife came and got me at the end of the day. Went back with a jack and took the drivers side rear tire off, grabbed the caliper and it was all sorts of floppy. Bottom bolt gone and top bolt was starting to get lose from me "stopping" in the parking lot trying to figure out what was going on.
So Thursday night I pulled the tire off, figured out what was going on. Couldn't find a replacement bolt. Took the caliper off to grab the old bolt, to make sure the new bolt matched the old one. Put the tire back on and left it there for the night.
Friday went to dealership to get new bolt. Got off work, home eat and change. Back to work to pull tire back off, pull rotor off to check, found crack on inside of rotor, cleaned everything off, put everything back together. Checked all the rest of the caliper bolts. It stayed at work again Friday night.
Sat morning went a picked it up, went home to grab "old" rotors, took them to O'Reillys to have them turned just for peace of mind at this point. Back home to pull both rears off, dissemble, clean again and back together for the third time with ample amounts of Permatex Threadlocker on caliper bolts.......and now they will be checked with every oil change.
Fun few days.
. I immediately noticed the A/C working better, a plus because it was 105* today.
