Brake Fluid

100% Synthetic Racing Brake Fluid – DOT 4

FEATURES:

• High Boiling Point: 312°C / 594°F
• Application: Suitable for hydraulic brake and clutch systems.

TYPE OF USE:
Designed for all types of hydraulic brake and clutch systems that require a non-silicone synthetic fluid. Engineered to handle the extreme temperatures generated by racing brake systems (both steel and carbon) and hydraulic clutch systems. Also compatible with conventional steel disc brakes and standard hydraulic clutch actuators. Exceeds DOT 3 and DOT 5.1 standards, except for viscosity at -40°C / -40°F.

PERFORMANCE:

• Standards: FMVSS 116 DOT 4, ISO 4925 (5.1, 4 & 3), SAE J1703
• Thermal Resistance and Stability:
  • The MOTUL RBF 600 FACTORY LINE offers an exceptionally high dry boiling point of 312°C / 594°F, surpassing the requirements of DOT 5.1 non-silicone (260°C min / 500°F min) and DOT 4 (230°C min / 446°F min) standards, ensuring reliable braking performance even under extreme conditions.
  • Wet Performance:
    • The fluid also boasts a high wet boiling point of 205°C / 401°F, exceeding the DOT 5.1 non-silicone (180°C min / 356°F min) and DOT 4 (155°C min / 311°F min) standards. This helps maintain effective braking in wet conditions, as brake fluids like DOT 3, DOT 4, and DOT 5.1 tend to absorb moisture from the air, reducing their boiling points and increasing the risk of vapor lock. The wet boiling point is measured after adding 3% water, simulating fluid condition after one year of use.

RECOMMENDATIONS:

• Drain Interval: Follow manufacturer recommendations and adjust based on usage.
• Mixing: Avoid mixing with lower-performance polyglycol-based brake fluids. Do not mix with silicone-based (DOT 5) or mineral-based fluids (LHM).
• Storage: Keep brake fluid in its original, tightly sealed container to prevent moisture absorption.
• Handling: This product is chemically aggressive. In case of contact with skin, paint, or varnish, rinse thoroughly with water.

PROPERTIES:

• Color: Amber
• Viscosity at 100°C (212°F): 2.5 mm²/s
• Viscosity at -40°C (-40°F): 1,750.0 mm²/s
• Dry Boiling Point: 312.0°C / 594.0°F
• Wet Boiling Point: 205.0°C / 401.0°F

100% Synthetic Racing Brake Fluid – DOT 4

FEATURES:

• High Boiling Point: 325°C / 617°F
• Application: Ideal for hydraulic brake and clutch systems.

TYPE OF USE: Suitable for all hydraulic brake and clutch systems requiring non-silicone synthetic fluid. Specifically engineered to withstand the extreme temperatures generated by racing carbon and ceramic brakes while minimizing air intake for brake cooling. Also compatible with conventional brakes using steel discs and standard hydraulic clutch actuators. Exceeds the requirements of DOT 3 and DOT 5.1 standards, except for viscosity at -40°C / -40°F.

PERFORMANCE:

• Standards: FMVSS 116 DOT 4, SAE J1703 / J1704
• Thermal Resistance and Stability:
  • The MOTUL RBF 660 FACTORY LINE offers an exceptionally high dry boiling point of 325°C / 617°F, surpassing the standards for DOT 5.1 non-silicone (260°C min / 500°F min) and DOT 4 (230°C min / 446°F min), ensuring reliable braking performance even in extreme conditions.
  • Aerodynamic Efficiency:
    • This brake fluid enhances aerodynamic performance by reducing the need for brake cooling air scoops.
  • Wet Performance:
    • With a wet boiling point of 205°C / 401°F, this fluid outperforms the DOT 5.1 non-silicone (180°C min / 356°F min) and DOT 4 (155°C min / 311°F min) standards, maintaining effective braking in wet conditions. DOT 3, DOT 4, and DOT 5.1 fluids absorb moisture from the air, lowering their boiling points and increasing the risk of vapor lock. The wet boiling point is measured after adding 3% water, simulating the fluid's condition after one year of use.

RECOMMENDATIONS:

• Drain Interval: Follow manufacturer recommendations and adjust based on usage.
• Mixing: Avoid mixing with lower-performance polyglycol-based brake fluids. Do not mix with silicone-based (DOT 5) or mineral-based fluids (LHM).
• Storage: Store brake fluid in its original, tightly sealed container to prevent moisture absorption.
• Handling: This product is chemically aggressive. In case of contact with skin, paint, or varnish, rinse thoroughly with water.
