It sounds like the caliper is sticking. When you depress the piston, it should be a smooth process. It it sticks, replace the caliper. Also, make sure the slides are clean and lubericated on the caliper. That can cause it to hang up too. If you feel that is the case, keep the caliper, purchase new hardware for it, clean and lube it, and it should be fine.
