I don't remember the year but it was a 12HP Dingo Deuce Model 612. Here is the linkage setup but it is difficult to see all the parts. I have other pictures of it in my profile Album and you can see what the kart looked like before I restored it. I could not find a parts breakdown for my specific caliper so if he has the same one not sure this will help much. Mine was Manco part number 8543 or "23" on the picture below.
