Hey - I spent $400 plus this weekend on having my "defective" calipers replaced. My car is an 04' with 55k miles on it...Rear brakes had been squealing for a couple weeks and were looking very worn compared to front brakes. Mechanic said my rear calipers were too tight (?) and applying too much pressure, even when not breaking, causing the uneven wear on the brakes/rotors. After checking out this site, I've seen it stated several times calipers shouldn't have to be replaced. Just seeking some insight and also putting this info out to others having brake/caliper issues.

The rear pads on the 3 wear faster than the fronts because they're a softer organic compound than the front pads, not because the calipers are faulty. The uneven wear is also a common issue. Sounds like your mechanic may have tried to take you for a ride.
