My trick for a stuck brake bleeder screw actually worked

Had a 2012 F-150 in the bay with a rear bleeder that wouldn't budge. I've snapped them before trying heat or an impact. This time, I tapped the screw head with a hammer a few times, then used a regular wrench and a small bottle of penetrating oil I keep warm on the radiator overnight. It broke free on the first try without rounding it off. Some guys say heat is the only way, others swear by vibration first. What's your go-to method for a seized bleeder before you risk breaking it?

Remember my buddy's old Jeep? He soaked a stuck one in ATF and acetone for a week, then just tapped the wrench with his palm and it came right out.

Ever think about the wrench itself? A cheap, slightly loose box end can round things off before you even feel it. A snug six-point socket on a good ratchet gives you that honest feedback, so you know you're twisting the screw and not just stripping its head.
