Most parts dweebs don't know enough to be able to identify the brakes even if you bring them in. There aren't many illustrated brake books around anymore, and the ones that do exist often aren't easy to find stuff in. Hell, most parts counter people don't even know where the books are. It's much easier to call A1 Cardone with a casting number from the caliper and ask what kind of car it's from, but even that's a stretch for most people. (I work parts at O'Reilly's)
The reason I want a pic of the caliper and bracket is because Scarebird has a kit that uses Ranger rotors and S10 pads/calipers. I'm not a big fan of the kit, but at least parts are easy to come by.
