The question to ask did you replace the caliper as a complete unit from the mounting bracket bolts . If so then the caliper may not be sliding on the two bolts that position it on the mount bracket. If this is not allowed to slide free (rusted up) then after you apply the brakes the caliper will be pulled into position but when the brakes are released the caliper cannot centralise and so one side of the pad is held on the disc rotor.. It is a matter or taking out the long bolts ,one at a time, and cleaning and lubricating the pins so that the caliper is free to move.

You will have to take the wheel off, then try to use a latge screw driver to pry between the old pads and the rotor to push the old pads back some, this will allow you to remove the caliper easier later. Next get a T-45 socket and remove both the top and bottom bolts from the back of the caliper. Tilt the brake caliper at the top or the bottom (it different for both side), and slide it off. Then you can just remove the pads. Be careful to notice that the shims on the caliper slide are different from top to bottom, don't mix them up. Pull the caliper slide pins out and inspect the boot for hole or cracks and the pins for rust, replace if any of these condition exist. Use some brake silicone grease to lube the slide pins and put a little into each boot and put the slide pins back in. Check the rubber boots on the caliper pistions to make sure they are not leaking any fluid or ripped. Use one of the old brake pads and a C-clamp to push both pistons on one caliper back in until they are flush. Check to make sure that no fluid leaked out of the caliper pistons while they were being pushed back in. If you want to do what is call a pad slap only then you can install that pads at this time but that is not recommended. It is recommened that you measure, check and turn the rotors if at all possible or replace them, the wheel seals and check and repack the wheel bearings.

1. Loosen lugs to wheel with wheel on the ground. Remove AFTER jacking the wheel into the air.
2. 2 bolts hold brake caliper to the suspension. Located on the inboard side of caliper. Usually is a regular hex bolt or an allen head. You may need to persuade them loose at first with a hammer or extra leverage.
3. caliper can be lifted off rotor exposing the pads. Be sure to note how the pads look in place so you can replace the new ones in the correct spot.
4. Depress the caliper piston completely back into cylinder with large channel lock pliers. be careful not to scar in any way.
4. put small amount of lube grease on bolt when reinstalling.
Good luck.. say a prayer and go for it.

By "sticking" I am assuming that you mean that the brakes are staying applied (calipers are not releasing)and burning the brake pads and rotors up.
The most common cause of this is brake hoses.
The hoses that connect your calipers to the steel brake lines have an inner lining and a reinforced outer "shell". sometimes the inner lining tears loose from the outer shell inside the hose. (It cannot be seen by "looking" at the hose.) The inner lining then starts to act similar to a "heart valve" where it allows fluid to be pushed down into the caliper, then collapses inside the hose, blocking the fluid from returning to the master cylinder when the pedal is released. This can happen just because of the age of the hose, but is more commonly caused by someone allowing the caliper to hang by the hose while replacing the brake pads without using anything to support the weight of the caliper.
To diagnose this condition, raise and support the vehicle and remove the wheels. Make sure that the transmission is in "Park" (Automatic Transmission) or "Neutral" (Manual Transmission) and apply the parking brake. Then start the engine and apply the service brake. (Press HARD on the pedal) Shut the engine off, release the service brake and open the bleeder screws on the calipers. If brake fluid squirts out of the bleeder screw under pressure, then the hoses are the cause of the calipers not releasing.
Testimonial: "I don't think I would have ever considered the brake lines. I've never seen one go bad. Your help is greatly appreciated!"
