My uncle told me to always use a torque wrench on bleed valves, and I'm glad I listened

He was a mechanic for 30 years and said 'if you strip that fitting, you're in for a bad day.' I was working on a Cessna 172's brake system last month and almost just used a regular wrench. I grabbed the torque wrench instead and set it to the spec in the manual, 35 inch-pounds. It clicked right away and the valve seated perfectly without any fuss. Anyone else have a simple tip from an old timer that saved your butt?

Ever notice how the old timers always have these weirdly specific rules? My grandpa insisted on a quarter turn back after tightening any plumbing fitting. Seemed pointless until I didn't do it on a garden hose and cracked the spigot. They've just seen all the ways things can go wrong, so their advice is like a shortcut past the mistakes. It's never about the big dramatic stuff, just these tiny habits that stop problems before they start.

Oh man, that quarter turn thing is real. My dad always said to never force a screw that's fighting you, just back it out and check the threads. I thought he was just being fussy until I stripped a bolt on my bike frame. Had to drill it out, whole huge mess. Those little rules are like cheat codes they learned the hard way.
