I decided to paint my calipers and got a case of the "might-as-wells". I am re-building my calipers, and have hit a snag. How do you get the pistons through the boots after the boots are installed? The manual tells you what to do, and not how to do it. The new boots are so tight that the pistons won't go through them. Is there a trick I'm missing. HELP!!!!!!!!!!!!!!!!
