The way I handle seized brake caliper bolts changed after a job in Tucson

I used to just hit them with an impact and hope for the best, which snapped a bolt on a 2015 F-150 last year. Now I soak them in PB Blaster overnight and use a MAP gas torch for a full minute before even trying. Has anyone found a better method for those rusted-on bolts without damaging the bracket?

Yeah, soaking them is key. I read a forum post where a guy swore by a 50/50 mix of acetone and transmission fluid instead of PB Blaster, said it creeps into the threads way better. Heated it just like you do after that soak. I've been meaning to try that mix myself on the really bad ones. The torch is a must though, that heat breaks the rust bond.

So we're just making salad dressing for bolts now?
