100% Synthetic Racing Fluid DOT 4
Very high boiling point : 325°C / 617°F
For hydraulic actuated brake and clutch systems

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).

PERFORMANCE
STANDARDS : FMVSS 116 DOT 4 / SAE J1703
Extreme thermal resistance and stability : Very high boiling point (325°C / 617°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 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 (205°C / 401°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 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.
