Mine did this in California. Not freezing. I was out of town driving home. Noticed resistance when leaving the parking lot. Figured it was the e brake but didn't have a choice but to hit the highway. Smelled my breaks burning up and pulled over. Had a shop disconnect my e brake. Been disconnected ever since. I do have an auto though so I guess I don't need it.
Replace the sticking caliper. The e-brake mechanism on one of mine stopped releasing and had to swap the caliper.
