Motul RBF 660 Racing Brake Fluid

Motul RBF 660 Brake Fluid is 100% synthetic racing brake fluid (DOT 4) for use in extreme temperature & racing applications. It is suitable for 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 - 40°C).

EXTREME THERMAL RESISTANCE AND STABILITY

Very high dry boiling point (325°C / 617°F), 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

High wet boiling point (204°C / 400°F) far exceeds the requirements of DOT 3, 4, and 5.1, enabling brake efficiency while rainy. Reduces the risk of “vapor lock”. Amber in color.

Do not mix DOT 4 brake fluid with silicone (DOT 5 silicone base) or mineral base fluids (LHM).
