The 100% synthetic polyglycol formulation is suitable for hydraulic brake and clutch systems requiring non-silicone DOT 4 fluid.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt for Extreme Brake Temperatures\u003c\/h2\u003e\n\n\u003cp\u003eRepeated hard braking converts a tremendous amount of energy into heat. As brake-fluid temperature rises, conventional fluid may begin to boil and create compressible vapor inside the hydraulic system.\u003c\/p\u003e\n\n\u003cp\u003eMotul RBF 700 is formulated to resist this condition during track driving, racing, and other severe-duty use. Its high boiling point helps maintain a firmer, more predictable pedal through heavy braking zones and repeated high-temperature stops.\u003c\/p\u003e\n\n\u003ch2\u003e637°F Dry Boiling Point\u003c\/h2\u003e\n\n\u003cp\u003eFresh Motul RBF 700 has a dry boiling point of 637°F, or 336°C. This high temperature capability provides substantial resistance to boiling when the fluid is new and the braking system has been properly flushed and bled.\u003c\/p\u003e\n\n\u003cp\u003eThe dry boiling point is particularly important for race vehicles that receive frequent brake-fluid changes and operate under sustained high brake temperatures.\u003c\/p\u003e\n\n\u003ch2\u003e401°F Wet Boiling Point\u003c\/h2\u003e\n\n\u003cp\u003eBrake fluid is hygroscopic, meaning it naturally absorbs moisture from the atmosphere. As moisture content increases, the boiling point gradually decreases.\u003c\/p\u003e\n\n\u003cp\u003eMotul RBF 700 maintains a wet boiling point of 401°F, or 205°C, providing strong temperature resistance even after controlled moisture absorption. Regular fluid replacement is still essential for maintaining maximum performance.\u003c\/p\u003e\n\n\u003ch2\u003eConsistent Pedal Feel Under Heavy Braking\u003c\/h2\u003e\n\n\u003cp\u003eWhen brake fluid begins to boil, vapor bubbles can cause a soft, long, or inconsistent pedal. RBF 700’s temperature resistance helps reduce the likelihood of vapor formation during repeated braking events.\u003c\/p\u003e\n\n\u003cp\u003eThis supports more consistent brake modulation, allowing the driver to apply and release braking pressure with greater confidence throughout a race or track session.\u003c\/p\u003e\n\n\u003ch2\u003e100% Synthetic Polyglycol Formula\u003c\/h2\u003e\n\n\u003cp\u003eMotul RBF 700 is manufactured from a synthetic polyglycol base.

This commonly includes race cars, track-day cars, time-attack vehicles, rally cars, and high-performance vehicles equipped with aggressive brake pads and tires.\u003c\/p\u003e\n\n\u003cp\u003eA street vehicle that does not experience sustained high brake temperatures may not require a racing fluid with this level of boiling resistance. Always follow the vehicle manufacturer’s required brake-fluid specification.\u003c\/p\u003e\n\n\u003ch2\u003eMotul RBF 700 Compared with RBF 600 and RBF 660\u003c\/h2\u003e\n\n\u003cp\u003eMotul RBF 700 sits above RBF 600 and RBF 660 in Motul’s racing brake-fluid range for maximum dry boiling performance. Its 637°F dry boiling point is intended for severe braking conditions where fluid temperature management is critical.\u003c\/p\u003e\n\n\u003cp\u003eRBF 600 remains a proven performance option for many track-day and competition vehicles, while RBF 660 offers increased temperature capability. RBF 700 is the strongest choice when maximum boiling resistance and consistent performance at extreme temperatures are the priority.\u003c\/p\u003e\n\n\u003ch2\u003eBrake Fluid Maintenance\u003c\/h2\u003e\n\n\u003cp\u003eRacing brake fluid should be replaced more frequently than ordinary street fluid because repeated heat cycles and moisture absorption gradually reduce performance. Vehicles used in competition may require fluid replacement or bleeding before each event, depending on operating conditions and team maintenance procedures.\u003c\/p\u003e\n\n\u003cp\u003eUse fluid only from a clean, newly opened container. Once opened, brake fluid begins absorbing moisture from the surrounding air and should not be stored indefinitely for future use.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs Motul RBF 700 a DOT 4 brake fluid?\u003c\/strong\u003e\u003cbr\u003e\nYes.
