I need new pads for all four wheels, so I went to Autozone (http://www.cadillacforums.com/forums/#) website. And for rear pads I got to choose with 1 pistion caliper or 2 piston caliper. Is there any way to find out what I've got other than actually take the old pads out and look at the piston(s)?

no, but 1 piston is highly possible
