MOTUL RBF 660 is a high-performance fluid specially designed to withstand the extreme temperature generated by racing carbon and ceramic brakes while allowing minimized air entrance for brake cooling. It has a very high dry boiling point (325°C / 617°F), exceeds the requirements of the standards for DOT 5.1 and 4 brake fluids, and therefore enables effective braking even in the toughest of conditions.
For all types of hydraulically actuated brake and clutch systems requiring non-silicone synthetic fluid. Also suitable for conventional brakes with steel discs and for conventional hydraulic clutch actuators.
Exceeds DOT 3 and DOT 5.1 standards requirements, except for viscosity at -40°C / -40°F.
