Ultra racing fluid to change more frequently than a simple brake fluid, high boiling point at 328 ° C.
Racing Brake Fluid 660
Factory Line
100% Synthetic Competition Fluid - DOT 4
Very high boiling point: 328 ° C / 622 ° F
For brake and clutch control
USES
All hydraulic brake and clutch control systems for which synthetic fluid
silicone free is recommended. Specially designed to withstand the extreme temperatures generated by carbon or ceramic brakes while allowing less air inlets for brake cooling. Also suitable for conventional brakes with steel discs and for controls
hydraulic clutches. Greatly exceeds DOT 3, DOT 4 and DOT 5.1 standards (except for the -40 ° C viscosity of DOT 5.1).
PERFORMANCE
STANDARDS FMVSS 116 DOT 4 / SAE J1703
Extremely high thermal resistance and stability:
The very high boiling point (328 ° C / 622 ° F) of MOTUL RBF 660 FACTORY LINE is higher than
conventional fluids DOT 5.1 (260 ° C / 500 ° F mini) and DOT 4 (230 ° C / 446 ° F mini), and therefore allows
maintain braking efficiency even when the brakes are under extreme stress. Better aerodynamic performance of cars by reducing the intake of cooling air from the brakes.
Efficiency in rainy weather:
The very high wet boiling point (204 ° C / 399 ° F) of MOTUL RBF 660 FACTORY LINE is
superior to conventional fluids DOT 5.1 (180 ° C / 356 ° F mini) and DOT 4 (155 ° C / 311 ° F mini), and
therefore makes it possible to maintain braking efficiency in rainy weather. DOT 3, DOT 4 and DOT 5.1 brake fluids have the property of absorbing humidity from the air, which lowers the boiling point and increases the risk of the appearance of the "vapor lock" phenomenon.
The wet boiling point is measured after moistening the product with 3% water.
USAGE TIPS
Avoid mixing with brake fluids based on polyglycols.
Do not mix with mineral (LHM) and silicone (DOT 5 silicone base) liquids.
Aggressive chemical product towards hands, paints and varnishes.
In case of contact with the skin, rinse thoroughly.
