Motul RBF 660 Factory Line – High-Performance Synthetic Brake Fluid

Premium Protection for Extreme Braking Conditions

Engineered for motorsports and high-performance driving, Motul RBF 660 is a cutting-edge 100% synthetic brake fluid designed to handle the intense heat of carbon-ceramic brakes, track abuse, and aggressive street driving. Its ultra-high boiling points (617°F dry / 399°F wet) prevent vapor lock, ensuring consistent pedal feel even under repeated hard braking.

Key Features & Benefits

✔ Race-Proven Formula – Optimized for track use but compatible with steel-disc street brakes and hydraulic clutch systems.
✔ Superior Heat Resistance – Outperforms DOT 3, DOT 4, and DOT 5.1 standards (excludes -40°C viscosity).
✔ Minimized Moisture Absorption – Reduces air entrapment for better cooling and longevity.
✔ Broad Compatibility – Mixes safely with DOT 3/4 fluids (not DOT 5/silicone-based).

Ideal For:

• Track/race cars with carbon-ceramic brakes
• High-performance street vehicles
• Heavy-duty braking systems (e.g., turbocharged or towing applications)

Why Choose RBF 660?
Unlike conventional fluids, Motul’s synthetic formula resists degradation under extreme temps, giving competitive racers and spirited drivers unmatched reliability. Pair it with aggressive pads and rotors for a fail-safe braking system.

Note: Not recommended for standard daily drivers under moderate conditions.
