This is 2003 Volkswagon Jetta. The wrench for the caliper bolts is a 7mm allen wrench, not a hex key like I kept saying. The tapping of the set screw with the ballpeen hammers is to vibrate the rust from the inside threads on the screw. I tried to remove the screw without tapping it first and I almost stripped it. After about 10 hits with the hammer, it came right out. I upgraded brake pads to ceramic pads because they produce a lot less brake dust.
