Purpose and Specifications

Motul RBF 600 Factory Line is a top-tier DOT 4 brake fluid built for high-performance braking in cars, motorcycles, and race vehicles. This 100% synthetic fluid handles extreme heat from track days or spirited driving, with a dry boiling point of 312°C (594°F) to fight brake fade and vapor lock during hard stops. Its wet boiling point of 204°C (399°F) keeps brakes reliable even after absorbing moisture over time.

Each 500ml bottle is nitrogen-filled at the factory to boost shelf life up to 5 years unopened and prevent contamination. It exceeds DOT 4, DOT 3, and DOT 5.1 standards (except low-temp viscosity), making it perfect for hydraulic brake and clutch systems with steel or carbon brakes.

• Prevents brake fade: Stays stable above 300°C for consistent pedal feel on track.
• Quick recovery: Cools fast between hard braking sessions.
• Versatile use: Suits racing, street performance, and daily drivers pushing limits.

When to Use / Replace?

Use Motul RBF 600 for track days, autocross, or any driving where brakes hit over 200°C regularly. Replace every 12 months or 10,000 km in performance use, or sooner if you notice softer pedals—brake fluid absorbs water, dropping its boiling point and risking fade. Flush the system fully when switching fluids to avoid mixing issues.

Pro tip: Ideal temps: Operates best from -40°C to over 300°C, flowing smoothly in cold starts while resisting heat buildup.

FAQ

Is Motul RBF 600 safe for my street car?
Yes, it's great for performance street cars, but flush yearly due to its water-absorbing nature—keeps brakes sharp longer than standard DOT 4.

What's the shelf life?
Up to 5 years sealed thanks to nitrogen packaging; once open, use within 1 year or 10,000 km.

Can I mix it with other brake fluids?
No—always flush completely. Mixing lowers performance and boiling points.
