Do the pistons on the front calipers push in flush with a rebuild or new pads or do they stick out a bit when fully recessed ? I searched some threads but didn't see anything pertaining to this. The reason I ask is the dealer who just did the rear brake recall job showed me a picture of the pistons out about 1/4 or 3/8 inch and said pads are way low and will grind the rotor soon. they didn't remove the calipers, a week earlier I had them off to replace front tire and don't remember being concerned about the pads. The parts page shows some long piston cups. Any help is greatly appreciated.
