Cracked a stubborn 737 brake line yesterday and this old-timer watched me fight it for 20 minutes before saying something
He just says 'you're trying to muscle it, but that line wants to be coaxed not forced.' I was about to snap a fitting so I backed off and tried his way, gently working it back and forth with some penetrating oil. Took maybe 3 more minutes and it came loose clean. Been wrenching for 6 years at MRO in Atlanta and that little tip saved me a whole lot of headache. Anybody else have something like that where a simple piece of advice from a veteran totally shifted how you approach a job?
