One can't really make an error in pushing the piston back during a pad swap because if you haven't pushed the piston back far enough you won't be able to place the new pads in, so it will be a no go from the start. Once the new pads are in and you depress the brake pedal, fluid pressure will push the pistons out and they will make contact with the pads. In other words, I don't see how there can be an installation error if your brakes are working fine apart from this small vibration issue, which will most likely go away once the carbotech compound is fully transferred to your rotors.
