Motul 1/2L Brake Fluid RBF 660 - Racing DOT 4

Very high dry boiling point of 622F (328C) and a wet boiling point of 399F (204C). For all types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Specially designed to resist extreme temperature generated by racing brakes (carbon and ceramic) only allowing a minimal air entrance for brake cooling.

• TYPE OF USE: 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 minimizing air entrance for brake cooling. Can be also used with conventional steel discs and clutch systems actuators. Widely exceeds DOT 3, DOT 4 and DOT 5.1 standards (except for DOT 5.1 viscosity at - 40C).
• PERFORMANCES:
• STANDARDS : FMVSS 116 DOT 4 / SAE J1703
• Extreme thermal resistance and stability :
• Very high boiling point (328C / 622F), superior to conventional DOT 5.1 fluids (260C / 500F mini) and DOT 4 (230C / 446F mini)
• Enables effective brake even in extreme conditions.
• Better aerodynamic performance by reducing air entrance for brake cooling on cars.
• Efficient when rainy:
• Very high wet boiling point (204C / 399F) superior to conventional DOT 5.1 non-silicone base fluid (180C / 356F mini) and DOT 4 (155C / 311F 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 percent 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.
