Highest Dry Boiling Point On The Market Today

AP Racing Radi-CAL R4 racing brake fluid has the highest typical dry boiling point, at 340º C (644º F), of any racing brake fluid currently available on the market today. Radi-CALR4 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 DOT3 and DOT4 racing brake fluid, but for maximum product performance your braking system should be thoroughly purged with R4 fluid.
