Well we installed some new rotors on my car about 2 weeks ago as well as the pads. Ive had a squeak in my front left tire and took it off today to find the vibration backing on the pad had slipped out and was rubbing on my rotor (can see in the bottom picture). Anyways, every time i want to take my caliper off i have to do it the hard way because 1 bolt wont come off and is stripped on the inside AND outside. Star bits, pressure grips, anything you can think of we've used to try get it off and it just strips it more and more so its almost a perfect circle inside and out. The info i want is.....what size is this bolt and any suggestions as to how to get it out and where to find a replacment for it? Pictures below to show...
