Brake Fluid - Motul RBF 660 FL

The Motul RBF 660 FL is a high-grade non-silicone synthetic fluid developed to withstand the most intense thermal punishment encountered in motorsport and aggressive street driving. As experts in Performance Tuning & Modification, Ninth Auto Gear recognizes that brake system performance is critical for both safety and speed. This fluid boasts a very high dry boiling point of 622°F (328°C) and a stable wet boiling point of 399°F (204°C). This extreme heat tolerance ensures consistent pedal feel and eliminates the risk of dangerous vapor lock and brake fade during hard, repeated braking. The RBF 660 FL is suitable for all types of hydraulic brake and clutch actuators and is specially formulated to resist the extreme temperatures generated by professional-grade racing brakes—including carbon and ceramic systems—even when minimal air is allowed for cooling. Choosing this fluid is a key component of our professional Track-Day Prep philosophy, guaranteeing the reliability and quality required when you push your vehicle to its limits.
