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 WHEN RAINing. The very high wet boiling point of
