WARNING: This page is about a different car, the 2009 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.

Blow air gradually to remove the pistons. The pistons will rush out if a force of air is applied suddenly.
Cover the caliper body outer side with a cloth or similar materials. Blow compressed air through the brake hose installation area to remove the piston and piston boot.
