I'll be giving my trucks to my offspring many years from now. I have no doubt that regular brake lines can last many, many years. I use stainless steel brake lines and hardware (whenever possible), so that I will rest in peace when I rest in peace.
By the way, I had original 1948-1954 brake lines fail in VA in 1969-1974 (no salt used on the roads back then) but the lines were sometimes corroded from the outside and sometimes from the inside.
