Racing Brake Fluid 660
Factory Line
100% Synthetic Racing Fluid – DOT 4
Very high boiling point : 325°C / 617°F
For hydraulic actuated brake and clutch systems
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).
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.
