| abstract |
Low viscosity functional fluids are described which comprise borate ester glycols, glycols, and a set of corrosion inhibitors that include one or more triazoles, amines, inorganic borates, inorganic nitrates, and alkenyl succinic anhydride. The fluids are particularly well-suited for use as DOT 4 brake fluids and provide robust corrosion performance over an extended life, thereby reducing the frequency with which the fluids must be replaced. |
