I am helping a friend to repair the rather rusty braking system on his 95' punto 1.2-75 hp. I've got some problems with faulty brake load sensing valves. All the mechanical parts that "connect the valve" to the moving rear axel is "gone" - taken by the rust. Can someone help? I need to know how it should be. An exploded view, pictures or similar would help a lot. I am located in Norway. Not too much help to get here from the local Fiat dealer. Fiat is not very common over here....
