Brake caliper piston won't go back in?

[Rmk_RDR]

My 2011 pro brake caliper won't let me push the piston back in? I took it off and now it clamped tight and I bleed the fluid out and took the resivour cap off and the bleeding screw out and nothing so I took off the brake line and tried using a big channel locks on it and it barely moved but then went right back out as soon as I released it so how do you get that piston back in?? Thanks

I noticed when pushing mine back in the piston tried cocking or goin in not straight so maybe try with a brake pad in place or peice of metal to push the piston back square. Damage could already be done to the bore though.

I've tried that and the piston won't go in at all

I haven't had mine off, is it a double piston, one on each side?

Single piston. C-clamp works best against an old pad. Bet it's cocked and binding. Possible that a corrosion ridge is snagging it. Torn down that far, might be a good time to just pull the piston and inspect.

Well I got it I had a brain fart and didn't realize I could push on the outside of the brake pad it went right in no problem I just hope I didn't wreck anything because the piston was binding thanks guys
