Motul RBF 660 – Racing Brake Fluid for Extreme Performance & Heat Resistance

Motul RBF 660 Factory Line is a high-performance, fully synthetic racing brake fluid specifically developed for extreme motorsport conditions, where very high braking temperatures are common. With an exceptionally high dry boiling point of 325°C (617°F), RBF 660 ensures consistent, fade-free braking performance in the harshest racing environments – from circuit racing and rally to drift and time attack.


Key Benefits:

• Ultra-High Dry Boiling Point (325°C) – Minimises the risk of vapor lock and brake fade, maintaining braking performance under prolonged high temperatures.
• Consistent Pedal Feel Under Load – Delivers stable hydraulic pressure and response, even during extended sessions and aggressive braking.
• Superior Thermal Resistance – Maintains fluid integrity and performance during repeated high-temperature cycles.
• Fully Compatible with DOT 4 Systems – Can be used in all braking systems that require DOT 4 brake fluid, including ABS-equipped systems.
• Motorsport-Proven Reliability – Trusted by professional teams worldwide for its race-winning consistency and performance.


Built for Motorsport. Ready for High-Performance Road Cars.

While designed for competitive motorsport, Motul RBF 660 is also an ideal upgrade for high-performance road cars, track day builds, or any vehicle where reliable braking under pressure is essential. Its low compressibility and extreme temperature tolerance make it a top choice for drivers who demand the most from their braking systems. Please be advised, if using RBF660 Racing Brake Fluid for a performance road car, we recommend more regular fluid change intervals when compared to OE (or equivalent) / Performance Brake Fluid.
