Motul RBF 660 Performance Brake Fluid

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.

EXTREME THERMAL RESISTANCE AND STABILITY: The very high boiling point (328°C / 622°F) is superior to conventional DOT 5.1 fluids (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini) enabling effective brake performance even in extreme conditions.

VERY EFFICIENT WHEN RAINY: The very high wet boiling point (204°C / 399°F) superior to conventional DOT 5.1 non-silicone base fluid (180°C / 356°F mini) and DOT 4 (155°C / 311°F mini) enables to keep efficient braking in wet conditions.

Brake fluids tend to absorb humidity from the air, which reduce boiling point and increase the risk to get to “vapor lock” phenomena. The wet boiling point is measured by humidifying the product with about 3.5 % of water.
