Removing brake piston

[Pink_Floyd]

I have a brembo 4 pot caliper and 1 of the pistons won't move, any suggestios as to how to remove it?. I have taken the caliper off the car and split it in two so that I can gain access to the piston, but whats the best way of getting it out. tried air from a foot pump but that wouldn't shift it.

Air should normally do the trick (used a small 12V tyre compressor a couple of weeks ago myself). And I put sometimes the pistons that came out back in and block them in a way that the sticky one gets a lot of air pressure. If still not ok, would push the piston in and try again (plan is that the movement has helped to free it), and as a last resort give it a couple of heat cycles and keep trying to remove it during it.

Be carefull, if it frees, it can jump out quite quickly.
