A trick for stuck brake bleeder valves that actually worked for me
Had a 2007 Silverado come in yesterday with a rear caliper that wouldn't bleed. The bleeder valve was completely seized, and I was about to just replace the whole caliper. Before I did, I remembered an old timer telling me to heat the caliper body around the valve, not the valve itself, and then tap it with a hammer while it's hot. I used my propane torch for about 30 seconds on the metal right next to the valve, gave it a few light taps with a small ball-peen, and it broke free without snapping. Saved the customer the cost of a new caliper and me a bunch of time. Has anyone else had luck with this method, or do you have a different go-to for frozen bleeders?

It's like a magic trick, but with more fire and less chance of a rabbit dying.

Oh man, that heat and tap method is a lifesaver. I learned it the hard way after snapping two bleeders clean off on an old Ford truck. I was so mad I almost threw the wrench. Now I reach for the torch before the brute force every single time. It feels like cheating, but it works.

Used to think heating stuff up was overkill until a bleeder valve on my Jeep turned to dust. Now I'm a total convert. That little bit of heat breaks the rust bond without wrecking the threads. Saves so much time and cussing. It's one of those tricks you wish you learned way sooner.
