With a little persuasion from a rubber mallet I got the caliper off. Still need to figure out what I have so I can get new pads. There's no marking on the pads.

This started with the wear indicator on the inside pad rubbing the rotor and squealing. Now that I have the pad out it looks like there's plenty of pad material before wearing to the rivets. Can I just bend the wear indicator a little and put it back together?
