Hello everyone, i recently got myself a zetor 5711 thats been sitting in a barn untouched for 20 years. Its not in a bad shape, currently im doing installations to put new pressure and temperature gauges as well as lamps and blinkers. Everything else is in a good condition, even the wiper motor except the output shaft that needs to be changed. The part that is kinda tricky to me is the handbrake and i suspect that the bands are too worn that it cant be engaged. i dont know if i should try to change it but it seems like a hell of a job so i came here to ask for some advice or is it even worth fixing as a quality of life feature. It also needs a new paint job and i dont know what paint to use to make it look like factory. any suggestions?
