Hello, does the piston have two slots machined into it for a tool to fit in to turn it?

If it has the cutouts to turn the caliper pistons and you don't have the shop tool you can use a pair of pointed nose vise grips, push in while turning clockwise, you need to push in until the threads engage and the it will be easier going all the way down.
