No real story here. Some inexperienced wrench messed up, whatever shop he works at (this time jiffy lube) is going to foot the bill and he will be looking for a new job.
The vehicle owner is a little naive/inexperienced himself 'I never heard of a mechanic test driving a car after a brake job!' C'mon man, every shop does that, it's standard practice.
The first shop I worked at, it was at night, only me and another guy, he was just pretty new fresh out of highschool tech class. He did a simple oil change, front end repair and rotate on a mustang, with instructions to make sure it no longer pulled violently. Minutes after the test drive started, he came back in with someone else (don't know who) and carried a jack, a torque wrench and socket outside. Doesn't matter what shop it is crap happens
