Caliper bolts are notorious for being hard to remove. They live in the worst environment. Being the rust belt, or constantly heat / cold soak, or the gorilla that last installed them.
Tool debt, yep working the Ford truck dealer. Family had ford's, I always GM guy.
Ford paid everything for first born boy. I started at flat rate $27.50 an hr.
Unlike a lot of the horror stories, the service manager was a fair straightforward manager. As a young guy he started on heavy crane repair.
Once had a boxvan in, diagnosis- one dead cylinder. 1700 miles out of warranty. He asked what do you want to do? Me " The other cylinder's are great, change the bad one". " Ok, pull it and do it, I'll tell parts".
So he warrantied the whole job, Ford agreed.
I got stuck, or assigned alot of not quite usual jobs.
The motor home RVs built on Ford chassis.
The special ordered parts, that went to paint for custom color, then ready install. Get paperwork, parts on cart, pull customer high end Explorer into bay. Look at parts, look at Explorer, oh no. Look under body, no fittings, no attachment points.
Parts ordered, custom painted, except..... Her year is one year prior to this optional part. They don't fit! Get this, her dad buys 10 new trucks each year from my dealership, big company. I don't know who took the bullet for that screwups. The service manager said "can you me it make work? What do need?"
I gave him list, and started layout. 45 minutes later a tool hardware rep shows up opens the back of van, " I was told to give you whatever you need". So what was a 1 hour job turned into 4.5 , I never found out what they told her or big cheese dad, but it was a laugh. Always had lot's of work back then.
