Lol, the rear brakes screw in, this is the way pretty much every rear brake works. I just use needle nose pliers and a lot of 4 letter words to spin them and its always fine .
Fronts are easier than the rears but you need to make sure you have a good 18" or longer breaker bar to get the goddamn caliper bolts off.
To compress the calipers themselves I just use a big set of channel locks. I also always do a power bleed when I'm done. Bought a Motive 1 person bleeder kit and it works great for this, you just have to make sure you get it with the 3 prong Ford specific cap since the universal caps are all junk.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
