I have been hired to do a brake job on a Zetor 5211 farm tractor in about 2 weeks. My only other experience with Zetor has been an oil change and a water pump replacement - easy jobs. Anybody familiar enough with Zetor (a Czech company) to either advise me or lead me to a service manual? There is not a Zetor dealer in this area and the owner is a horse guy, not a mechanic or even an equipment guy.
