If you know not only what a torque wrench is, but how to use it properly you will likely have no trouble changing brake pads.
The feeling I get is that auto work goes much much deeper though, and I am interested in resources that offer that knowledge.
Full engine rebuilds, or even troubleshooting intermittent CANbus issues, sure. But basic maintenance like brake pads or changing out a failed alternator just require basic hand tools and some minor knowledge you can get from youtube.
