MOTUL RBF 660 Factory Line Brake Fluid is a high-performance non-silicone synthetic brake and clutch fluid specifically developed for demanding motorsport and high-performance driving applications. Designed for all hydraulically actuated brake and clutch systems requiring a synthetic fluid, it delivers exceptional resistance to extreme operating temperatures.
Engineered to withstand the intense heat generated by racing carbon and ceramic braking systems, MOTUL RBF 660 helps maintain consistent braking performance even under the most severe racing conditions. Its formulation also allows for reduced air ingress in braking systems designed for cooling, improving overall system reliability and pedal consistency.
While optimised for motorsport use, it is also suitable for conventional braking systems with steel discs and standard hydraulic clutch systems. It exceeds the performance requirements of DOT 3 and DOT 5.1 standards, with the exception of viscosity at -40°C, making it a proven choice for track, competition, and high-performance road use.
