Product Description

The Motul 100949 RBF 600 DOT 4 Racing Brake Fluid is a premium, fully synthetic fluid engineered for high-performance braking systems where extreme temperatures and consistent pedal feel are critical. With a very high dry boiling point of 312 °C (594 °F) and a wet boiling point of 204 °C (399 °F), this brake fluid helps prevent vapor lock and brake fade during rigorous use. Its formulation exceeds standard DOT 4 requirements and meets key industry specifications, making it suitable for both motorsport and demanding street applications.

Filled with nitrogen at the factory to extend shelf life and reduce contamination risk, Motul's RBF 600 fluid delivers stable performance across a wide temperature range. It's compatible with all hydraulic brake and clutch systems requiring DOT 4 fluid and mixes with DOT 3/DOT 4 bases (but must not be mixed with silicone-based DOT 5 fluids). Its consistent viscosity and high resistance to thermal degradation make it a favorite choice among racers, performance enthusiasts, and anyone pushing their braking system to the limits.

This brake fluid is universal by design - it's not vehicle-specific and can be used wherever DOT 4 brake fluid is specified. Ensure you follow all manufacturer guidelines for brake fluid type, and always replace fluid in complete system servicing for best performance and safety.
