Anyway...when I did mine I blew them out with the little air compressor I use to put air in my tires, you know, the type that plugs into the cigarette lighter. They come out with a vengence, so I c-clamped some pieces of wood to stop them (per recommendations). Piece of cake them to use your fingers to pull them out. I don't know, using pliers and such around pistons makes me nervous.
