Not enough room for disc pads and rotor

Hello

I decided to try and replace the disc pads myself, however there only seems to be a piston on one side and it doesn't seem to go back in completely there is 3 mm sticking out, I can put the pads in but no space in between them....

I have tried a plastic tyre remover and screw driver and feels like it just won't go back any further. The brake unit is Shimano BR-M596. I bought compatible pads.

What's my next step?

Thanks in advance
Vicky

    Put the old pads back in so you don't damage anything, get a big screwdriver or something sturdy, and twist hard.

    Also you can see the piston isn't sitting square, pull the lever to try and ease it out a bit so it sits square again.
