Caliper Piston stuck

[christofis135i]

Taking apart some calipers to get powder coated and one of the pistons black top piece came off without the piston and it's stuck inside the cylinder. Any ideas on how to get it out?

Do you have access to a compressed air gun? put some padding / cloth inside the caliper/around the stuck piston, and shoot compressed air into where the brake line goes (maek sure the bleeder screw is shut tight)

Obviously wear all safety equipment/take precautions etc - the piston should shoot out under pressure.

4/6 pistons are already out so compressed air wouldn't do anything. I accidentally pushed it back in lol

go to home depot and get the rubber expanders that have a wing nut on the end that fit into the space. you can block off the ones that are already out and use the compressed air for the others.

These kind of things
