Everything needs to be checked. The entire brake system should just be replaced. I would trust wheel cylinders or calipers that sat in the same position for that long. Rust as well as moisture in the system destroy brake components from the inside out. Replacing the parts isnt that expensive especially if its taken as a long term project. All hoses/bolts and rubbers components should be replaced. I would grease everything that has a grease fitting and lube everything else that moves. The wiring needs to be closely inspected. Rats,mice,squirrels etc love to nest in old cars/trucks that sit in a field. All fluids need to be replaced. Change the oil/transmission fluid and gear oil. Drop the gas tank and clean it out. If its fairly rusty inside get a replacement. Sitting untouched is harder on a vehicle than driving the hell out of it daily. Also plan on new tires. Even if they look ok they are dry rotted and probably not the safest.
