I was doing my brakes today and ran into this exact problem. The new pads are so much thicker than the used ones, and my pistons were out pretty damn far. I was extremely frustrated until I saw this video, and then I was finally able to push back the caliper pistons after watching this. Saved my day, really.
@JOSHUFC38 i think its rust inside the system, from inside the caliper cavity, even from the piston, also its brake oil that has oxidized if it has had contact with air, and is too acidic , makes rust maybe on the piston. also the oil may have become damp , i guess from air , or water leaking by piston seal, or if air got in the system before from a leaky hose or connection or untight bleed nipple, but I know little about this. just from reading and by bad memory and imagination.

How does dirt enter the brake fluid system if it is a closed system are is it? When you open the bleeder you mention this.

Question about pushing back the piston . What if you have a brembo caliper ? how would you do it ?
