Was driving my 81 around the other day and started to notice some brake drag. Pinpointed it down to the two front disc brakes. I took the calipers off and was able to compress the piston once with a clamp and then after that couldn't. I replaced the mc last summer with a remanufactured one. I am going to try to replace the rubber lines with new ones today. Just wondering if anybody has had this happen before, or have a suggestions? It has manual brakes and I bled everything when I put in the new mc. Just think its weird its both sides. Thanks for any suggestions.
