Castrol React SRF Racing Brake Fluid Ultra-High Wet Boiling Point Makes Castrol SRF A Standout Castrol React SRF Racing Brake Fluid is an ultra-high performance brake fluid popular with many of the highest performing auto racing teams around the world. The key to Castrol SRF brake fluid's performance is its silicon-ester technology. Not only is it less hygroscopic (i.e., it absorbs less water) than typical glycol-based brake fluids, Castrol SRF also reacts chemically with any absorbed water to further reduce its adverse effects on high-temperature braking performance. The result is an almost unheard of 518° F (270° C) wet boiling point, more than 100° F higher than most other racing brake fluids! Exceeds SAE 1703, ISO 4925, JIS K2233, FMVSS No. 116 DOT3 and DOT 4 specifications. Note: Castrol SRF is not a silicone-based brake fluid (i.e., DOT 5) and is compatible with most factory brake systems and fluids, including DOT 3 and DOT 4 fluids. Always follow vehicle manufacturer's recommendations when adding brake fluid. Castrol React SRF Racing Brake Fluid Typical Properties: Dry Boiling Point: 590°F (310°C) Wet Boiling Point: 518°F (270°C) Superior anti-vapor lock properties One-liter (1000ml) bottle

Motul RBF 700 Racing Brake Fluid Motul RBF 700 Factory Line Racing Brake Fluid is a high-performance DOT 4 fluid engineered to maintain consistent braking power under the extreme temperatures produced by racing and high-performance brake systems. Its exceptionally high 637°F dry boiling point helps resist vapor formation during intense braking, while a 401°F wet boiling point provides dependable performance as the fluid absorbs moisture over time. The 100% synthetic polyglycol formulation is suitable for hydraulic brake and clutch systems requiring non-silicone DOT 4 fluid. Built for Extreme Brake Temperatures Repeated 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. Motul 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. 637°F Dry Boiling Point Fresh 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. The dry boiling point is particularly important for race vehicles that receive frequent brake-fluid changes and operate under sustained high brake temperatures. 401°F Wet Boiling Point Brake fluid is hygroscopic, meaning it naturally absorbs moisture from the atmosphere. As moisture content increases, the boiling point gradually decreases. Motul 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. Consistent Pedal Feel Under Heavy Braking When 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. This supports more consistent brake modulation, allowing the driver to apply and release braking pressure with greater confidence throughout a race or track session. 100% Synthetic Polyglycol Formula Motul RBF 700 is manufactured from a synthetic polyglycol base. It is intended for conventional hydraulic brake and clutch systems requiring DOT 4, DOT 3, or compatible non-silicone synthetic brake fluid. It must not be confused with silicone-based DOT 5 brake fluid, which has different chemistry and compatibility requirements. Suitable for High-Performance Brake Systems RBF 700 was developed for the extreme temperatures generated by demanding racing brake systems, including applications using high-performance iron, carbon, or ceramic brake components. It may also be used in high-performance road vehicles when the manufacturer specifies a compatible DOT 4 brake fluid and the vehicle is maintained according to the appropriate service schedule.

RBF 700 is intended for vehicles that repeatedly generate brake temperatures beyond the comfortable operating range of standard street brake fluid. This commonly includes race cars, track-day cars, time-attack vehicles, rally cars, and high-performance vehicles equipped with aggressive brake pads and tires. A 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. Motul RBF 700 Compared with RBF 600 and RBF 660 Motul 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. RBF 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. Brake Fluid Maintenance Racing 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. Use 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. Frequently Asked Questions Is Motul RBF 700 a DOT 4 brake fluid? Yes. Motul RBF 700 meets the FMVSS 116 DOT 4 standard and SAE J1703 requirements. What is the dry boiling point of Motul RBF 700? The dry boiling point is 637°F, or 336°C. What is the wet boiling point? The wet boiling point is 401°F, or 205°C. What is the difference between dry and wet boiling point? Dry boiling point measures fresh fluid with minimal moisture. Wet boiling point represents fluid after controlled moisture absorption and gives a better indication of performance after the fluid has been in service. Can Motul RBF 700 be used in a street car? Yes, when the vehicle requires a compatible non-silicone DOT 4 fluid. However, racing fluid should still be replaced at appropriate intervals and may require more frequent maintenance than standard street fluid. Is RBF 700 compatible with DOT 3 fluid? Its polyglycol chemistry is generally compatible with conventional DOT 3 and DOT 4 fluids, but mixing reduces the benefit of the higher-performance fluid. A complete flush is recommended when upgrading. Can it be mixed with silicone DOT 5 fluid? No. Silicone-based DOT 5 fluid is chemically different and should not be mixed with RBF 700. Is this the same as DOT 5.1 brake fluid? No. RBF 700 is classified as DOT 4 despite exceeding the minimum boiling-point requirements of many conventional DOT 5.1 fluids. Can Motul RBF 700 be used in a hydraulic clutch? Yes, when the clutch system specifies a compatible DOT 3 or DOT 4 non-silicone hydraulic fluid. Will higher-boiling brake fluid fix a soft pedal? Not necessarily. A soft pedal can also be caused by trapped air, worn components, flexible hoses, fluid leaks, pad knockback, or mechanical problems. The system should be properly inspected and bled. How much fluid is needed for a complete flush? One 500 mL bottle may be enough for some compact systems, but many vehicles require more than one bottle for a thorough flush. The exact amount depends on the vehicle and bleeding procedure. How often should racing brake fluid be changed? Replacement frequency depends on heat exposure, moisture, event schedule, and maintenance practices. Dedicated race vehicles may receive fresh fluid or a thorough bleed before every event. Can an opened bottle be saved for later? Brake fluid absorbs moisture after opening. Keep the cap tightly sealed and use it promptly, but fresh unopened fluid is preferred for critical racing service. Does brake fluid damage paint? Yes. Brake fluid can damage painted and finished surfaces. Wipe spills immediately and follow the vehicle manufacturer’s cleaning recommendations. Note: do not mix synthetic DOT 4 brake fluid such as Motul RBF 660 with DOT 5 silicone-based or any mineral-based brake fluids.
