Motul Brake Fluid RBF660

Motul RBF 660 Factory Line Racing Brake Fluid - 500ml

Extreme Thermal Stability for Competitive Motorsport

When braking demands exceed the limits of standard racing fluids, Motul RBF 660 Factory Line is the answer. Engineered for the most punishing thermal environments—including professional endurance racing and cars equipped with aggressive big brake kits—this fluid is designed to maintain a rock-solid pedal when others begin to fade. RBF 660 isn't just about a higher boiling point; its specialized formula is designed to perform with maximum precision, ensuring consistent hydraulic pressure even under the heat-soak of competitive circuit racing.

What’s Included in the Box:

- (1) 500ml Bottle: Nitrogen-purged and foil-sealed for purity.

The Motul Advantage

- Professional Grade Heat Resistance: Features a staggering dry boiling point of 328 degrees C (622 degrees F), offering one of the highest safety margins in the industry against vapor lock.

- Aerodynamic Focus: Designed to withstand extreme temperatures with less reliance on external air cooling, allowing for more efficient brake ducting on race-spec vehicles.

- Consistent Performance: High wet boiling point of 204 degrees C (399 degrees F) ensures reliability in high-humidity environments or as the fluid begins to age.

- Maximum Modulation: Optimized viscosity allows for precise brake feel and modulation, which is critical for threshold braking on the limit.
