I have a 1983 380 SEL. After sitting about 7-10 days and sudden cold weather hitting Ohio I started it up and started to go in reverse for about 5 feet and then the brakes would not allow me to go any further (parking brake?) If I gave it some gas the back end would rise; I was able to go forward.

I finally gave it a lot of gas and "broke loose" it made some rubbing noise for about 200 yards and then back to normal.

Question: What is the smartest way to get rid of my parking brake, I do not need this to happen again. Could this be a sticking caliper?

Thanks!
