Hello everyone,
I finally got around to checking the driver side front brake to see why it sticks all the time. Upon removing the caliper I noticed that the pistons are severly rusted and corroded to the point that they don't move at all! I have already purchased replacement calipers to rebuild but need to know how to hook up my air compressor to force out the pistons. I assume that it isn't to difficult and before I wasted more time figuring it out I thought I would ask the experts. What is needed and how is it done? This is my first attempt at disc brakes and don't want to mess things up.
I already have the rebuild kits from GT Source. As always thanks in advance for your help!

if your air nozzle has a rubber tip, then, with the caliper off the car, make sure the bleeder valve is closed and pump air in through where the steel brake line hooks up.

On the note of safety put a board or heavy blanket over the caliper while you are forcing the caliper out with air. Sometimes those things really come out at you.
