Gleaner k combine brakes

I have a question for somebody knowledgeable and Gleaner combines. I just bought one and it works great but it's got absolutely no brakes . it's only got the one pedal that goes to what I believe to be the transmission? I ordered new brake shoes but since I don't have a computer AGCO parts book doesn't show up for crap on my phone... I don't know if anybody else has had the same issue but I'm looking to repair the brakes and I don't know what else I need or how it goes together. if anybody has a picture or advice on how to do it I'd really appreciate it! I live on a relatively hilly property so I'm not really wanting to move it until it's fixed LOL. thank you!
