I was on my way home last night from work and out of no where my passenger side rear brake lock up on me. Not a good thing when one is travling 60plus mph. With it locking up on me it sent me in to a slide side ways. Not even thinking I turned the wheel the other direction and it send me in to a slide the other direction. This entire thing happened while going around a long curve on the Interstate right before my exit. I make it off the interstate and get things stopped just off the ramp. I get out and find my tire is half way off the rim. At that point I thought I had a blow out but I did not hear anything. I go to take the rim off and when I do the brake caliper is all makred up and has metal all over it. I then look at the rim and the inside of the rim is tore up. I then see a large crack in the rim about 3 inches long. I look at the brake caliper and what do I find out. One of the bolts that holds the caliper on broke, this casued the caliper to slam into the rim causing the rim to spilt and crack. I guess then the caliper then got slammed back into the rotor and this locked up that tire. I can tell you this I'm sure that if it was not raining some I think that truck would had flipped when it went side ways at 60plus mph the truck was completely side ways. When I was changing the tire a Cop pulled up to see what was going on when he saw the rim and caliper he when back up to the interstate and looked at the marks. He came down and wanted to shake my hand for still being in one piece and keeping it up right. I guess I have my teens years to thank for that and all the times we would halla@@ on the country roads and slide all over. Something like that really makes you think about life and how one second you are here and the next it could be all over.
