The Chevrolet Service bulletin has one on these about operation and fill instructions. Appearently they need to be pumped up by operating the lever and fluid added until full. I can try to scan the bullentin and e-mail it to you if you want. I can also scan the parts list which has a cut away view but only for the single action type for you as well. Let me know as I do not know how to post that stuff on here yet.
