My parking brake from the factory was never impressively tight. The last 10,000 miles the brake seemed to tighten up to a respectable amount of clicks while setting it. One night a few weeks ago I heard my pads dragging while driving. I got out and noticed one wheel was heavily coated in brake dust and smelled hot. I figured my parking brake cable was bound up or caught. Gave it a series of pulls, some pretty hard to see if it would loosen up. I guess it eventually worked and the pads loosened up. A few days later I noticed it was extremely loose. I removed the center console today and noticed the adjustment cables were very different. Is it normal to have the cables different lengths or did I stretch/break a cable?
