RBF660 Factory Line Brake Fluid

RBF660 Factory Line Brake Fluid

PART NUMBER: 101666, 101667


  • 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.


  • 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.
