MOTUL RBF 660 Factory Line Brake Fluid is 100% Synthetic Racing Fluid - DOT 4 for extreme temperature & racing applications. All types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Widely exceeds the DOT 3, DOT4 and DOT 5.1 standards (except for DOT 5.1 viscosity at - 40C).
EXTREME THERMAL RESISTANCE AND STABILITY:
Very high boiling point (325C / 617F), superior to conventional DOT 5.1 non silicone base, DOT 5 silicone base fluids, and DOT4. MOTUL RBF 660 enables effective braking even under extreme conditions.
EFFICIENT WHEN RAINY: Very high wet boiling point (204C / 400F) far exceeds the requirements of DOT 3 & 4 & DOT 5.1 enabling brake efficiency while rainy. Reduces the risk of the "vapor lock" phenomena. Amber in color.
Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM).
Volume: 500ml
