For years I was using channels and Cclamps to push that piston down. And it worked just fine. Then I dug up an old set I bought that pimpps the piston down and I was like.. are you kidding. So the moral is you dont need all them fancy tools to get the job done.
I have taken the old brake pad and used a C-clamp and slowly tightened it, and the piston goes down slowly. Had to be careful I didn't push fluid back thru the master cylndr. spotman
