Motul RBF 700 Factory Line Brake Fluid

Motul RBF 700 is a high-performance Factory Line Brake Fluid developed to offer highly consistent and maximum braking power at extreme brake temperatures generated by carbon and ceramic racing brake discs systems. Motul RBF 700 allows to minimize air vents of the brakes, thus improving aerodynamic drag, and it can be used with conventional steel discs, as well as clutch system actuators. Motul RBF 700 Factory Brake Line Fluid meets DOT 4 standard, allowing the fluid to be used in high-performance vehicles for everyday use road applications. Product Overview: *100 percent synthetic racing brake fluid—DOT 4 * For hydraulic actuated brake and clutch systems * Offers highly consistent and maximum braking power * Very high boiling point: 336 degree C / 637 degree F and is superior to all conventional brake fluids DOT 5.1 (260 degrees C / 500 degree F mini) and DOT 4 (230 degree C / 446 degree F mini), therefore enables effective braking in most extreme conditions * Offers extreme thermal resistance and stability * Enables efficient braking in wet conditions—brake fluids tend to absorb humidity from the air which reduces boiling point and increase the risk of "vapor lock" phenomena or so called "spongy braking". The wet boiling point is measured by humidifying the product with 3 percent of water Important Note: Avoid mixing with polyglycol based brake fluids. Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM). Store brake fluid in its original container and tightly closed to prevent moisture absorption.
