Thats a good article on piston removal. My method was a little different, since they were getting powder coated. I didn't remove the pistons until the caliper was split in two halves. Then I just plugged all holes, but one for air. Next I wrapped a shop rag around the half (to catch pistons), and eased the air pressure on until they popped. This can get dangerous fast
, if not done carefully.
