'07 Cobalt LS. No ABS, no traction control.
I have (IMO) excess drag when I manually rotate the passenger side front wheel. Inspecting, those pads have lost a lot of material. (inner & outer equally; over ~1500 miles.) The driver's side rotates (IMO) too freely, and the pads have not worn significantly. I don't see anything obviously wrong with either side. There is no discernible pull, either braking or not.
I suspect I need a new caliper. Even so, (a) is there a way to tell which one, and (b) I'd like to get a better picture of what would cause this mix of symptoms.
