Cadillac CTS First Generation Forum - 2003 - 2007 Discussion, Brake Job Fail in Cadillac CTS Coupe, Sport Sedan and Sport Wagon Forums; All was going well until the front passengers side Brake Caliper Bolt sheared and broke off in the Caliper Pin!!! ...
That shouldn't be hard. Why not use a stud extractor then replace bolt with similar one. Or better yet what I would do is tack weld a nut to it, if you don't have a welder any shop can weld a nut to it, you don't have to leave thigns like that.
I dont have those tools or the know how. Now I know for next time! Parts should be here this afternoon : )
Add this also for next time, get a vice grip and secure it ver well, it will get it done. And if that doesn't for any reason, if you have a bench vice, grap the stud with the bench vice and rotate the caliper bracket by hand it should come off.
