Donny, using the brake lever pressure is how I always remove the pistons. First of all I make sure reservoir is full, then remove calipers from rotors, then the spring in bottom of calipers if pistons are far enough back, then with short lengths of paint stirring sticks, I start pumping the brakes keeping all pistons the same using the paint sticks to stop one or the other. That way I can get them all to where they are just on the brink of popping out. Then it’s just a wiggle.
