Description

The Motul RBF 660 Factory Line brake fluid is engineered for the extreme demands of racing and high-performance braking systems. As a 100% synthetic DOT 4 fluid, it offers exceptional thermal resistance and stability, crucial for preventing brake fade under intense conditions. This racing-grade fluid boasts a very high dry boiling point of 325°C (617°F) and a wet boiling point of 205°C (401°F). These specifications significantly surpass conventional DOT 5.1 (non-silicone) and DOT 5 (silicone) base fluids, ensuring consistent performance even at elevated temperatures. The fluid complies with FMVSS 116 DOT 4 and SAE J1703 standards. Motul RBF 660 is ideal for any braking system requiring a fluid with superior resistance to vapor lock and heat-induced degradation. Proper fluid maintenance and replacement are essential for optimal braking performance and safety, especially in motorsport applications.
