Probably a couple of things.
First, you might need to pull the caliper off and make sure the arm pivots freely. If it does not, it will have to be cleaned and then lubed. It also needs to be adjusted so there is about .008 gap between the stationary pad and the rotor.

If you still have binding, then you will probably need to pull the caliper apart again provided that the lever action is firm.
What happens is corrosion builds up from the dot3 fluid attracting moisture. This occurs throughout the housing and especially in the groove where the rubber seal sits. A good brass brush will help you clean this out. If you got a dremel withe brass brush, go to town!. The corrosion comes out looking white.
