has anyone had to replace a defective caliper yet?, have 52K on my 06 sel, and turns out that caliper is bad (see my dba rotor and green stuff pads post). just had meineke look at brake and put new pads on all four and had same problem with stuck piston. thought they fixed it again, and went highway speeds for 40 miles and when got back to them for 3rd time today, left rear rotor was 329 degrees and the other 3 were 140 degrees. i know it can't be the paint job that was done prior to new rotors and pads being put on as brakes worked fine. didn't notic problem until installation of rotors and pads by a different meineke shop. not going to invest in painting this caliper, though as don't have time to waste nor money to rent a car for a day.
