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.
Note that R4 can be mixed with DOT3 and DOT4 racing brake fluids but for maximum product performance the brake system should be thoroughly purged with R4 fluid.
