100% synthetic fluid for hydraulic-actuated brake and clutch systems. Specifically designed to resist the high temperatures of actuated (steel or carbon) racing brakes and clutch systems. EXTREME THERMAL RESISTANCE AND STABILITY: the elevated boiling point of RBF 600 FACTORY LINE (312 C / 593 F) enables effective braking even under the extreme conditions of competition. VERY EFFICIENT IN WET CONDITIONS: the very high wet boiling point (216Éc / 420ÉF), is superior to conventional brake fluids and provides a particularly efficient braking system in rain and retards the apparition of vapor lock. NORMES : FMVSS 116 DOT 4 / SAE J 1703 / ISO 4925. Sold per bottle. We recommend 2 bottles when changing your complete system.
