Brake Fluid MOTUL RBF 660 (328°C) - Bidon 500ml

MOTUL RBF660 (328°C) - bidon 500ml

Quantité pour une bonne vidange et purges du circuit frein : 1L (2 bidon 500ml)

For all types of hydraulically actuated brake and clutch systems requiring non-silicone synthetic fluid.

Specially designed to withstand the extreme temperature generated by racing carbon and ceramic brakes while allowing minimized air entrance for brake cooling.

Also suitable for conventional brakes with steel discs and for conventional hydraulic clutch actuators.

Exceeds DOT 3 and DOT 5.1 standards requirements, except for viscosity at -40°C / -40°F.

STANDARDS FMVSS 116 DOT 4
SAE J1703 / J1704
Extreme thermal resistance and stability:
MOTUL RBF 660 FACTORY LINE very high dry boiling point (325°C / 617°F) exceeds the requirements of the standards
DOT 5.1 non silicone base (260°C mini / 500°F mini) and DOT 4 (230°C mini / 446°F mini), and therefore enables effective
braking even in extreme conditions.
Allows better aerodynamic performance by reducing the need for brake cooling air scoops on vehicles.
Efficient when rainy:
MOTUL RBF 660 FACTORY LINE very high wet boiling point (205°C / 401°F) is superior than the requirements of the
standards DOT 5.1 non-silicone base (180°C mini / 356°F mini) and DOT 4 (155°C mini / 311°F mini), and therefore
enables to keep efficient braking in wet conditions.
Indeed, DOT 3, DOT 4 or DOT 5.1 brake fluids have the property of absorbing moisture from the air, which reduces their
boiling points and increases the risk of “vapor lock” phenomena.
The wet boiling point is measured after moistening the product with 3% water in order to be representative of the state of
the fluid after 1 year of use.
