Sounds like you might have a caliper that is stuck and is not fully disengaging. If it is in the rear then you may have a bad rear caliper. Twoo things you can try. One is to crawl under the ca and adjust the tension two nuts on the emergency brake line. If that does not resolve the problem then remove the back tire and try to spin the drum or rotor whichever you may have. If it does not spin then try adjusting the e brake cable more if it still does not respond then you need to do a brake rebuild. Also does it pull while it is dragging? If it is then you will need to rebuild the brakes no matter what.
