Help with rounded bolt
Ugh...been trying to get my passenger-side rear caliper off and the two caliper bolts were looking pretty rounded. I tried a lot of Liquid Wrench and the 5/8 Craftsman wrench that's supposed to help with rounded bolts. Nothing but busted knuckles. You can't cut the bolt head off as the bolt would still be threaded into the back. Plus, I've got so much brake fluid and Liquid Wrench all over the parts that I don't want to use heat, either.
I was talking to my neighbor - who wrenches a lot on his car - and offered $100 if he could get them off.
No take.

If the bolts are accsessable enough then use a file or dremel grinder and put new flats on the bolts to get a six point socket on the bolts to loosen. Next size down English or metric doesn't matter.

Make sure your wrenching the right bolts. It's kinda easy to get on the bolts holding the caliper halves together, rather than the mount bolts. I've done it, sure many others have too.
Other than that, a rounded-bolt extractor and an impact driver...

I wouldn't worry about the fire from the oil. It will burn off, just keep a wet rag handy. That and an impact gun will free the bolt or break it. Either way you have removed the caliper...

I agree with fileing the head down just enough to hammer the next size smaller socket onto the bolt, this usually works for me. I've also used a hammer and chisel trying to hammer counter clock wise to get the bolt to spin. You could also try to easy out the bolt or reverse drill bit.
Good luck.

I work for Irwin's sister company so I have access to all of their tools. These work very well and are pretty much like doing the Dremel trick and going with another socket. These bite into the head of the bolt and extract the bolt. Little pricey for a one time use but they work.

Man, what a PITA...glad they're all off, now I can put on the new calipers and bolts.
