For correct oil/lubricant, go to the Castrol Lube Guide High performance polyglycol type brake fluid designed to provide superior braking performance in a variety of vehicles, especially those that operate at higher temperatures or under increased loads.FEATURES & BENEFITS High boiling point: Exceeds US FMVSS DOT 3 and DOT 4 specification requirements, and offers a performance reserve over brake fluids with lower boiling points. High vapour lock temperature: Greater protection against brake fluid vaporization Corrosion protection: Outstanding protection against corrosion caused by absorbed moisture that can cause rusting and failure of components High temperature stability provides a greater margin for safety because product performance will not fade under higher temperatures Controlled viscosity requirements: Under extreme s of temperature and operating conditions, the product will maintain an optimum operating viscosity to ensure greater safety Rubber swell control: Contributes to efficient operation of the braking system components Compatible with all other brake fluids that meet either DOT 3, DOT 4 or Super DOT 4 Specifications SPECIFICATIONS Australian Standard AS 1960-1976 Grade 1 FMVSS Class DOT 4 SAE J1704
