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 – 40°C).
The very high dry boiling point of 622F (328C) and a wet boiling point of 399F (204C). For all types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Specially designed to resist extreme temperature generated by racing brakes (carbon and ceramic) only allowing a minimal air entrance for brake cooling.
