Motul RBF 660 Factory Line is a racing brake fluid built for the extreme temperatures generated by carbon and ceramic racing brakes, with a very high boiling point of 622F (328C). It is specially designed to allow minimal air entrance for brake cooling, and can also be used with conventional steel discs and clutch system actuators.
Key Features
- Very high dry boiling point of 622F (328C), superior to conventional DOT 5.1 fluids at 500F (260C) minimum and DOT 4 at 446F (230C) minimum
- Very high wet boiling point of 399F (204C), superior to conventional DOT 5.1 non-silicone base fluid at 356F (180C) minimum and DOT 4 at 311F (155C) minimum
- Widely exceeds DOT 3, DOT 4 and DOT 5.1 standards, except for DOT 5.1 viscosity at -40C
- Standards: FMVSS 116 DOT 4 and SAE J1703
- Extreme thermal resistance and stability enables effective braking in extreme conditions
- Better aerodynamic performance by reducing air entrance for brake cooling on cars
- Non-silicone synthetic fluid for all types of hydraulic brake and clutch actuators
Applications and Notes
Brake fluids tend to absorb humidity from the air, which reduces boiling point and increases the risk of vapor lock. The wet boiling point is measured by humidifying the product with about 3.5 percent water. Motul advises avoiding mixing with polyglycol based brake fluid, and not mixing with silicone DOT 5 or mineral base LHM fluids. Store brake fluid in its original container, tightly closed, to prevent moisture absorption. This is an aggressive chemical product on hands, paint and varnish; if skin contact occurs, rinse thoroughly with water.
