Well it happened last week. My front drivers side brake caliper froze shut and practically destroyed the rotor. I tried to fix it and get it working properly again, but it still freezes from time to time. I'd like to use this as an excuse to get all new calipers, but ever kit I see for the contour is only selling front brake sets. I want at least two piston calipers this time, but don't want to speed an insane amout on a set. Any suggestions? I'll need new rotors too... so keep that in mind when making your decisions.
