The power-steering and brakes as used in the Deere 2520-3020-4020 is totally different than what is found in cars and trucks. The Deere systems has no mechanical connection, just hydraulic - so when the engine stalls, the steeingwheel does nothing, nor does the brake pedal. Deere did incorporate a hydraulic accumulator which gave a small reserve in case the engine stalled (very little at that). Usually, once a couple of years old, the accumulator's nitrogen charge was lost and they did nothing. In a car or truck, the basic steering and brakes will work without the engine running, just not as well. The automotive power is only power-assist, the mechanical steering is still there, and so is the hydraulic brake system.
In regard to crappy brake-lines, yeah, that's kind of interesting. In Europe, plain steel alloy brake lines are not allowed to be used. They use Monel which is highly rust-resistant. In the US, the OEM lines are treated, but they are not Monel. Then, if you buy a replacement from NAPA, or such, the lines are cheap crap and rust out in 18 months.
As far as Deere getting sued, they got sued over many things just as other companies have. It was usually kept quiet. I remember Deere getting in hot water over the full-hydraulic steering and brakes in the 2520-3020-4020 series. Also for the lack of parking brakes or shifter-locks in many later 30 and 40 series tractors, so we had to add brake and shifter kits. Also, Deere suffered from a large lawsuit that including every single crawler they ever made with the HL-R transmission including 2010s and 450s. I did many, many, updates on them.
