This is my first post i am 16 and getting ready to buy a 1974 chevy nova and the guy said that one of the calipers are locked up from just sitting in his garage and collecting moisture. now i know my fair share about cars but i wanted to come and check from the experts. ive herd alot of good things from here but anyways what will i need to do so i can unlock the caliper to drive it home when i buy it? im not sure so any ideas guys? thanks for the help
