Radi-CAL™ R4 Racing Brake Fluid 0.5 Liter

AP Racing Brake Fluids have been developed specifically for use under the arduous conditions encountered at the highest levels of motorsport. All AP Racing Brake Fluids are compatible with all hydraulic brake systems designed to conform to S.A.E. J1703 requirements. AP 551 can be used for either competition or road use. The Radi-CAL™ R4 Fluid has been designed to perform better than any other product at the extremes of heavy duty braking performance in the top levels of racing.With the highest dry boiling point of any racing brake fluid currently available, at 340°C (644°F), R4 stands alone. With outstanding resistance to vapour lock / pedal fade under the most exacting conditions. A higher vapour lock point means a firmer brake pedal at the extremes of brake temperature. Enhanced lubricity, means this fluid is an even better lubricant than PRF660 itself a market leader. This helps the life of the metal moving parts of the brake system and increases system efficiency.
