Back-off the adjuster on the lever arm.

yes it needs quite a lot of slack - if you ride about a mile that should get it nicely warm - then back off the MC rod until it's free 10mm lock nut and 8mm adjuster (or fingers) might need to take heel plate off for easy access (HP rearsets).
a good bleed won't hurt either

Get some brake cleaner in there and a big flat lever...

It will go...but the piston could be offline try to give it pressure from different points

ohh thats bad i can push mine by hand - so it slides and or pushes piston back just by holding caliper (and it still locks)

Leave the old pads in an put a flat lever in between the old pads. When you apply pressure it will be more even on the piston. Give the piston a good clean before though.

Too much fluid in the system possible ?
