AP Racing Radi-CAL R4 Racing Brake Fluid Among the Highest Dry Boilings Point On The Market Today AP Racing Radi-CAL R4 racing brake fluid has an ultra-high typical dry boiling point, at 644º F / 340º C. Radi-CAL R4 racing brake fluid has been designed to perform better than any other product at the extremes of heavy-duty braking in top levels of professional racing. AP Racing Radi-CAL R4 has outstanding resistance to vapor lock and pedal fade under the most exacting conditions. A higher vapor lock point means a firmer brake pedal at the extremes of brake temperatures. Enhanced lubricity means R4 is a better lubricant than other market-leading racing brake fluids. This helps extend the life of the metal moving parts in your brake system while increasing system efficiency. Radi-CAL R4 can be mixed with other DOT 3 and DOT 4 racing brake fluid, although for maximum performance your braking system should be thoroughly purged with R4 fluid. AP Racing Radi-Cal Pro R4 Brake Fluid Details: Manufacturer: AP Racing Manufacturer part number: AP-CP7005 DOT rating: DOT 4 Dry Boiling Point: 644º F / 340º C Wet Boiling Point: 383º F / 195º C Bottle Size: 500 ml (16.9 fl. oz.)

Motul RBF 660 Racing Brake Fluid Motul RBF 660 Brake Fluid is 100% synthetic DOT 4 racing  brake fluid for use in extreme high temperature & racing applications. It is suitable for all types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Widely exceeds the DOT 3, DOT4 and DOT 5.1 standards (except for DOT 5.1 viscosity at - 40°C). Extreme Thermal Resistance and Stability Motul RBF 660 has a very high dry boiling point (325°C / 617°F), superior to conventional DOT 4, DOT 5, and DOT 5.1 brake fluids. Motul RBF 660 enables effective high-speed braking even under extreme temperature conditions. Efficient When It Rains The high wet boiling point (204°C / 400°F) of Motul RBF 660 far exceeds the requirements of DOT 3, DOT 4, and DOT 5.1, enabling excellent braking efficiency while driving or racing in the rain. This also reduces the risk of “vapor lock”. 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.

Motul RBF 600 Racing Brake Fluid Motul RBF 600 is a 100% synthetic high-temperature DOT 4 brake fluid for hydraulic-actuated brake and clutch systems. RBF 600 is specifically designed to resist the high temperatures of steel or carbon-composite racing brakes and clutch systems. Motul RBF 600 far exceeds the standards of ordinary DOT 3 and DOT 4 brake fluid. The RBF 600 container is filled with nitrogen to increase shelf life and eliminate contamination while factory sealed. Its extremely high dry- and wet-boiling points help prevent vapor lock and brake fade during hard use. Extreme Thermal Resistance and Stability The elevated dry boiling point of RBF 600 (593° F / 312° C) enables effective braking even under extreme conditions like racing competition, mountain driving, etc. Very Effective in Rainy Conditions The high wet boiling point (420°F / 216° C) of Motul RBF 600 is superior to conventional brake fluids, providing particularly efficient braking in rain while reducing the risk of vapor lock. Note: do not mix DOT 4 brake fluid like Motul RBF 600 with DOT 5 silicone-based or conventional mineral-based brake fluids.
