General brake question

No offense to any mechanics on here, but I'm 54 years old and have found only about two "good" mechanics in my life. But I can tell lots of horror stories about "not good" mechanics. There should be a mechanic horror story thread, for people that like to gripe about that sort of thing.
None taken, I've probably worked with 10× as many bad techs as You could tell stories about, some of them are My age or older.....I marvel at how they could possibly have made it this far being that F'n awful, but then I see the equally awful writers & managers who suck & are sympathetic enablers, & then it becomes clear.....
