I was tryint to catch up with my friend with his new SS, and i was doing a good job, when he was braking of course. We were doing this for about 10 mins, untill when we came to a stop light and there was smoke comin frlom my right rear wheel. Havent had a chance to check it out yet becuz its dark out. Friend told me it was my caliper that froze up on me! Is it fixable, or do i have to replace it now?
