Motul RBF 600 Brake fluid is our most popular brake fluid.  It is a 100% synthetic fluid for hydraulic-actuated brake and clutch systems. Specifically designed to resist the high temperatures of actuated (steel or carbon) racing brakes and clutch systems. RBF 600 is an extreme high performance polyglycol brake fluid that far exceeds the standards of DOT 4. Each bottle is filled with Nitrogen, increasing shelf life and eliminating contamination while factory sealed.

EXTREME THERMAL RESISTANCE AND STABILITY:  The very high dry boiling point (312°C / 594°F) exceeds the requirements of the standards DOT 5.1 non silicone base (260°C mini / 500°F mini) and DOT 4 (230°C mini / 446°F mini), and therefore enables effective braking even in extreme conditions. 

VERY EFFICIENT WHEN RAINY: The very high wet boiling point (205°C / 401°F) is superior than the requirements of the standards DOT 5.1 non-silicone base (180°C mini / 356°F mini) and DOT 4 (155°C mini / 311°F mini), and therefore enables to keep efficient braking in wet conditions.

Indeed, DOT 3, DOT 4 or DOT 5.1 brake fluids have the property of absorbing moisture from the air, which reduces their boiling points and increases the risk of “vapor lock” phenomena.

The wet boiling point is measured after moistening the product with 3% water in order to be representative of the state of the fluid after 1 year of use.
