There are other ways to spread the pistons, but this tool is the absolute best. The Park Tool PP-1.2 Hydraulic Brake Piston Press is perfectly designed to safely press the pistons back into a hydraulic brake's caliper when replacing pads or bleeding the brake. It makes hydraulic disc brake maintenance and repair so much faster and easier than ever before. This is a great tool with an equally great design and will last you a life time. It's a very good investment for those who like to work on their own bike and an absolute necessity for those who are part of the industry.
