On Saturday after getting back from a week away I took my 08 for a drive after it sitting and noticed something was wrong with the front passenger wheel...vibration at 40mph but not slower or while applying brakes, car felt like it was pulling to that side and saw some smoke through windshield. Wasnt far from home yet so I went back and jacked it up, pads look like volcanic rock (prob from the heat), one of two pistons in caliper frozen and the other was leaking fluid from the rubber boot. So ordered new caliper and pads from RA, they arrived this morning and I installed. All well now. Old pads top, new pads bottom.
