1993 Owners manual 4X4 350

Hi folks, first time for me on this forum, and first time owner of an atv and I know there are other similar threads, but I could not find an answer, so am trying again. The Polaris site does not go back as far as 1993. I did download a service manual which is helpful, but doesn’t give me a clue as to how this thing should operate. We are in the Havelock Ontario area, and my first request for a part at a dealer (auxillary brake caliper seals) I was told it was discontinued. Looks like this will be an interesting journey!
