The "calipers" float on pins or bolts, and actually move slightly, realigning as the pads wear. If one pad is worn more than the other, the pins/bolts need to be pulled, caliper pulled, and a light coat of grease applied to the pins and sliding surfaces for the caliper.
It is sticking for sure.

Its probably that the calipers need a good cleaning. The outer portion of the caliper is floating. As the piston on the inner side presses the inner shoe, it causes a leverage affect on the outer caliper and its shoe. The outer portion of the caliper should be moving easily on the two bolts and sleeves that hold the assembly together.These get gummed up with rust, brake shoe dust, and road grime. Disassembly and a good cleaning should fix this type of problem. The only other situation that can cause this is that the piston on the inner portion is sticking. There is a tool to break these loose and remove the piston, but newer cars are different so do some research before attempting to do this fix yourself. After the piston is removed, the bore is honed slightly to remove rust and varnish buildup. The piston is wet sanded using brake fluid and 400 grit cloth paper to remove rust and varnish. The piston is then reinstalled with new seals, boot, and O-rings installed. This is a bit trickier than the caliper cleaning.

The bolts or pins that your caliper slides on are stuck and or the pads are sticking in the bracket that holds the brake pads in place. You don't really need the calipers if you can push the piston back into the caliper. Clean the rust off the pins, and all the places that touch the backing of the pads. Then you need to apply synthetic disk brake lubricant to all the places metal makes contact with metal. And finally install your new pads and new or resurfaced rotors.

Most likely you have a caliper sticking. This can be caused by scoring in the caliper piston(s) or sticking/binding on the slide mechanism. Generally the car will pull when you apply the brakes if this is the case.
If you are mechanically inclined, pull the caliper off and clean/lubricate the slider mechanisms and their surfaces. Use a high temperature grease...sparingly.

This is a common symptom of a "sticking" caliper. When the brake pedal is released, the caliper isn't sliding back away from the rotor. You really need to get it taken care of quickly, the next step is usually warped rotors, because the pads are constantly pressed against the rotors, causing them to get very hot.

The pistons in the calipers might be shot, you will need to get them rebuilt or replaced.

mine does that too,and my brakes are good.it has something to do with the thickness of your rotors too.if 1 side is thicker then the other side,then that pad will apply to the rotor before the next 1 will.

You definitely have a problem. Have a professional mechanic look at vehicle. This could be leading to a more serious repair.
