  • Overview
    • 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 - 40°C).

      STANDARDS : FMVSS 116 DOT 4 / SAE J1703

      PERFORMANCE

      Extreme thermal resistance and stability

      Very high boiling point (328°C / 622°F), superior to conventional DOT 5.1 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 on cars.

      Efficient when rainy

      Very high wet boiling point (204°C / 399°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 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 % 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
      • Colour: Amber
      • Dry boiling point: 328 °C / 622 °F
      • Wet boiling point: 204 °C / 399 °F
      • Viscosity at -40 °C (-40 °F): 1698 mm²/s
      • Viscosity at 100 °C (212 °F): 2.59 mm²/s
    • TYPE OF USE

      All types of hydraulic actuated brake and clutch systems in accordance with DOT 5.1, DOT 4 and DOT 3 manufacturers’ recommendations. Fluidity specially designed for anti-locking brake systems (ABS).
      STANDARDS:

      • FMVSS 116 DOT 5.1 NON SILICONE BASE, DOT 4 and DOT 3
      • SAE J 1703
      • ISO 4925 (5.1, 4 & 3)

      PERFORMANCE

      Long life fluid

      The high wet boiling point (187°C / 369°F), superior to DOT 4 (155°C / 311°F mini) and DOT 3 (140°C / 284°F mini) conventional fluids enables to use this product longer. Indeed, DOT 3 / DOT 4 and DOT 5.1 brake fluids have the property to absorb humidity contained in the air, which reduces their boiling points and consequently security. The wet boiling point is representative of the fluid after one year of use.

      Specially designed for anti-locking brake systems (ABS)

      The viscosity (820 centipoises at -40°C / -40°F) lower than DOT 4 (up to 1800 cp) and DOT 3 (up to 1500 cp) brake fluids allows an easier fluid circulation in micro-valves of anti-locking systems. Perfectly neutral with seals used in braking systems. Anti-corrosion.

      RECOMMENDATIONS

      • Mixable with DOT 3, DOT 4 and DOT 5.1 NON SILICONE BASE products
      • Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM)
      • Store brake fluid in its original container, tightly closed to avoid absorption of moisture
      • Aggressive chemical product if contact with hands, paint or varnish
      • If skin contact, rinse thoroughly with water
      • Drain Interval: 12 to 24 month as per manufacturers’ recommendations

      • Viscosity at 100°C (212°F): 2.1 mm²/s
    • TYPE OF USE

      All types of hydraulic actuated brake and clutch systems requiring a non-silicone synthetic fluid. Specially designed to resist to high temperature of racing actuated brake (steel or carbon) and clutch systems. Exceeds DOT 5.1 and DOT 3 standards also, except for viscosity at -40°C (-40°F).

      PERFORMANCE

      Extreme thermal resistance and stability

      The very high boiling point (312°C / 594°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 an effective brake even under extreme conditions.

      Efficient when rainy

      The very high wet boiling point (204°C / 399°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 an efficient brake system when rainy. Indeed, DOT 3, DOT 4 and DOT 5.1 brake fluids have the property to absorb humidity in the air, which reduces their boiling points and increases the risk to get to “vapor 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 with lower performances
      • 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 absorption of moisture
