You didn't mention if you bought new or rebuilt or performance or...?

Depending upon where you obtained the calipers they are probably the culprit. I've done loaded (rebuilt) calipers in the past on other vehicles and in one case they'd been sitting in the store long enough that there was corrosion built up in one of the calipers that caused the piston to stick and drag. FYI before you install anything other than a brand-new caliper I'd recommend opening the bleeder screw and pulling the cap off the hose connector, pouring in some proper fluid for your vehicle and then working the piston(s) back and forth several times by hand -- they should move freely, if not I wouldn't put them on my car. Might be worth removing yours and seeing if the piston(s) moves freely throughout the range of motion.

It's also possible that there is some small difference between the calipers you bought and the stock ones and/or they are not mounted properly (or there's a difference that prevents them from mounting properly) so they are "cocking" at an angle and forcing contact with a pad. If you remove the pads you'll see if they are hitting at an angle and if so, that's probably the issue.

Good luck!

RE: breakes and calipers

Thanks Greg,
I just find out that I used the wrong wheel bearings grease, it was not the right temperature. The guy who did the work pick the wrong grease. I am going to take it a part this weekend. I am hoping the bearings are ok!!!
