Motul 660 brake fluid enables effective braking performance in extreme conditions. With its very high-boiling point, Motul 660 resists the extreme temperatures generated by racing carbon and ceramic brakes. This formula's thermal resistance and supreme stability make it ideal for high performance racing applications. Motul 660 brake fluid exceeds DOT 3, DOT 4, and DOT 5.1 specifications. For all types of hydraulically actuated brake and clutch systems requiring non-silicone synthetic fluid. Specially designed to withstand the extreme temperature generated by racing carbon and ceramic brakes while allowing minimized air entrance for brake cooling. 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. PERFORMANCE SPECS Standards: FMVSS 116 DOT 4, SAE J1703 / J1704 Extreme thermal resistance and stability: Very high boiling point (328°C / 622°F), superior to conventional DOT 5.1 non silicone base / DOT 5 silicone base fluids (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini) Efficient when rainy: MOTUL RBF 660 FACTORY LINE very high wet boiling point (205°C / 401°F) is superior than the requirements of the standards DOT 5.1 non-silicone base (180°C mini / 356°F mini) and DOT 4 (155°C mini / 311°F mini), and therefore enables to keep efficient braking in wet conditions.
