Front brakes won't release

That was one of the other tests that I tried was loosening the master cyclinder and there was not any pressure release on the calipers.
When I pulled the dr diff kits it did show having to bend the tab for the outward pads some, but I have not tried that yet.
I do not know if they are new or rebuild, but i am going to assume they are rebuilt as most parts you get anymore are plus with the calipers I had to turn in the old ones to get my core charge refunded.
There was relief on both the bleed valve and the main line at the Mc at least to the point that I could turn the rotor with a little effort.
