Need Help 944 Front Brakes

[LOAF]

I am having problem dismantling my front brake assembly off a 87 non turbo 944..(This is still in question, but based on the trailing arm stamping of 87 and having single piston on Calipers would have to assume non-turbo).. If anyone has had experience with this, I would appreciate some help..
I was able to remove all the safety pins and take out the inside (Inboard) Pad.. I am having difficulty getting the piston to open up enough to properly get the outside (outboard) pad off..

Looked thru the web but all they talk about is sticking a prying bar between back of pad.. I looked at my caliper set up and felt that I probably do more damage this way..

Please help..
