Liquid Sodium chloride and rock salt used to de-ice winter roads break down and destroy steel tubing lines. Steel brake lines have had zinc, galfan, PVF (poly vinyl fluoride) and Nylon plating to protect them from the winter de-icing onslaught and still life expectancy for these steel tubing lines has fallen dramatically.
