TIL a trick for stuck caliper bolts from a guy at the Mid-Ohio swap meet
I was at the Mid-Ohio swap meet last month and got talking to a guy at a tool vendor's booth. He said for a caliper bolt that's seized but not rounded, try heating it with a torch for 30 seconds, then immediately tapping the bolt head with a hammer while you turn it. The shock from the tap helps break the rust bond. I tried it on a 2012 Silverado last week and it worked like a charm. Has anyone else used this method on other parts, like exhaust manifold bolts?
