500ml of Motul Racing Brake Fluid RBF660 325°C Factory Line 100% Synthetic Fluid – DOT 4
Long life 100% Synthetic Fluid specially designed for anti-locking brake systems (ABS).
Suited for all types of hydraulic actuated brake and clutch systems actuators requiring non-silicone synthetic fluid. Specially designed to resist to extreme temperature generated by racing carbon and ceramic brakes allowing
minimizing air entrance for brake cooling. Can be also used with conventional steel discs and clutch system actuators. Widely exceeds
DOT 3, DOT 4 and DOT 5.1 standards (except for DOT 5.1 viscosity at -
Very high boiling point : 325°C / 617°F.
Very high boiling point (325°C / 617°F), superior to conventional DOT 5.1 non-silicone base / DOT 5 silicone base fluids (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini) Enables effective brake even in extreme conditions. Better aerodynamic performance by reducing air entrance for brake cooling.
Very high wet boiling point (205°C / 401°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
while rainy. 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.
Avoid mixing with polyglycols based brake fluid. Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM). Store brake fluid in its original container, tightly closed to prevent moisture absorption. Aggressive chemical product if contact with hands, paint or varnish. If in skin contact, rinse thoroughly with water.
