Whilst i had the Drum off the front right I wanted to see the system in action, Now i understand this was a STuPid thing to do!
The pistons have pushed out further that they are meant to and they wont realease.
I have bled the system of the brake fluid and therefore the pressure but they wont budge.
I Dont know what to do now?

Use your finger and lift up the rubber covering the ends of the wheel cylinder. They must be twisted try to push the pistons back in they just have a small spring holding them. Otherwise buy a new wheel cylinder or a rebuild kit.
They have a spring two pistons and two rubber seals and the two end caps.
