MOTUL RBF 660 RACING DOT 4 BRAKE FLUID 500ML

MOTUL RBF 660 Racing Factory Line DOT 4 100% Synthetic Brake Fluid may be used for all types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Specially designed to resist to extreme temperature generated by racing carbon and ceramic brakes allowing to minimize air entrance for brake cooling. Can also be used with conventional steel rotors and clutch systems. Widely exceeds DOT 3, DOT4 and DOT 5.1 standards (except for DOT 5.1 viscosity at - 40°C).

PERFORMANCE

STANDARDS : FMVSS 116 DOT 4 / SAE J1703 & J1704 / ISO 4925

Extreme thermal resistance and stability:

Very high boiling point (325°C / 617°F), superior to conventional DOT5.1 non silicone base / DOT5 silicone base fluids (260°C / 500°F mini) and DOT4 (230°C / 446°F mini)

Enables effective brake even in extreme conditions.

Better aerodynamic performance by reducing air entrance for brake cooling for cars.

Efficient when rainy:

Very high wet boiling point (204°C / 400\°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 vapour lock phenomena. The wet boiling point is measured by humidifying the product with about 3.5 % of water.

RECOMMENDATIONS

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 skin contact, rinse thoroughly with water.

PROPERTIES

100% synthetic fluid, polyglycol bases.
