AP Racing Radi-CAL R3 Racing Brake Fluid


Designed For The Top Levels Of Motorsports

AP Radi-CAL R3 was developed for use in very-high-temperature racing conditions. Conforms to and exceeds FMVSS 116 DOT 4 and SAE J1703 and J1704. AP Racing Radi-CAL R3 Racing Brake Fluid is currently one of the most popular brake fluids at the highest levels of professional auto and motorcycle racing. It was specifically developed for coping with extraordinary temperatures, such as those encountered when running a carbon/carbon brake system.

To ensure that the fluid stays fresh, AP brake fluids are furnished in 500 ml (16.9 oz) easy-pour plastic bottles with double-sealed caps. When switching your fluid to AP Racing Radi-CAL R3, we recommend purging all of the old fluid from the system. Three to four bottles of fluid are enough to completely replace existing brake fluid and still have enough left over for a bleed at the track to remove any remaining air bubbles.
