Brake master cylinder ??? (pics)

put it in a vise, attach vise grips on it and use two wrenches like fulcrums. how is the piston held in on the new master???? a snap ring? should be. do you have a new pushrod rubber ratainer? if not take a piece of 1/4 fuel line and slice it the width you need and then put a little v notch in it(front to back) so it has room to compress...
