Motul RBF660 High-Performance Brake Fluid (325°C)

Motul Racing Brake Fluid is ideal for use in competition, on track days or on fast roads where braking systems are subject to extremely high temperatures. By increasing the boiling point the brake fluid is less likely to cavitate, which causes a soft pedal and reduces braking performance. Exceeds the DOT 5.1 specification for temperature resistance (260°C or 500°F).

This synthetic brake fluid offers an exceptionally high dry boiling point of 325°C (617°F) and a wet boiling point of 204°C (400°F), making it suitable for all types of hydraulic brakes and clutches requiring non-silicone fluid. Specifically designed to withstand extreme temperatures generated by racing brakes (whether carbon, ceramic, or steel), it ensures reliable performance even in demanding conditions with minimal airflow required for brake cooling.

We recommend this for you, if…

Whether you’re chasing speed on the street or on track, this brake fluid never skips a beat. Even when we cooked our brake pads and the paint on our brake calipers, it delivered firm and strong pedal feel. Suitable as a factory brake fluid replacement, it will keep up with your performance brake setup while being street legal and safe.

Did you know?
Regular fluid changes are essential and you should always store brake fluid in sealed containers. Why? All brake fluids are hygroscopic, meaning they absorb moisture over time, which can degrade performance and can lead to a “vapor lock” where vapor forms in worn-out brake fluid, potentially causing brake failure.

Suitable for all cars that require DOT 4 or DOT 5.1 brake fluid. Can be used for clutch systems actuators too.
