If you mean the sticking calipers, it was really only one that was sticking and I fixed mine by replacing it. The piston in the old one was well rusted and wasn't moving freely in the bore - especially when pushed all the way back in with the new pads. I was in a hurry at the time put I'm presuming I could have just replaced the piston and cleaned up the caliper, and I still have the intention of doing this with the old one....sometime
