AP Racing Brake Fluid R3
Radi-CAL R3 is suitable for all top levels of motorsport where abnormal temperatures are experienced.
Before using R3 fluid, any existing brake fluid should be drained completely from the brake system. The system should be thoroughly purged with new R3 and can be filled completely with new R3.
R3 has advanced moisture resistance properties, low levels of viscosity (for ease of bleeding), low levels of compressibility and meets DOT4 specifications.
