When they stick it's not always just a simple matter of freeing the off with a little grease. Every piston should be as free and I mean free one finger easy push in anymore and they will stick again. Water/moisture gets under the dust and sometimes the main seal, which will oxidise and swell, this places pressure on the seal which in turn makes the pistons stick.
Often the only way is to strip the caliper and clean out the rebate/s.
