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

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

Type of Use:

All types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Specially designed to resist extreme temperatures generated by racing carbon and ceramic brakes, allowing for minimal air entrance for brake cooling. Can also be 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).

Performance 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 braking 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 efficient braking in wet conditions
• Brake fluids tend to absorb humidity from the air, which reduces boiling point and increases the risk of vapor lock phenomena

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 in contact with hands, paint, or varnish
• If skin contact occurs, rinse thoroughly with water
