AP Racing Brake Fluid




We carry the R2, R3 & R4 range of AP Racing Brake Fluid

Radi-CAL™ R4 brake fluid

Designed to perform better than any other brake fluid during the heavy-duty braking experienced in the highest levels of international motorsport, R4 brake fluid offers outstanding resistance to vapour lock and pedal fade. Its dry boiling point of 340⁰C (644⁰F), ensures that it’s suitable for the most demanding applications. Delivering a firmer brake pedal at extreme temperatures, R4 offers enhanced lubrication, compared to the previous market leader, prolonging the life of metal components within the system and improving overall efficiency.

Radi-CAL™ R3 brake fluid

Suitable for all top levels of motorsport, where abnormal temperatures are experienced, R3 features advanced moisture resistance properties, low levels of viscosity (for ease of bleeding), low levels of compressibility and meets DOT4 specifications. Radi-CAL™ R3 replaces AP Racing’s PRF660 brake fluid.

Radi-CAL™ R2 brake fluid

With a dry boiling point exceeding 300°C, R3 has been developed for racing applications where high operating temperatures are to be expected, which includes using carbon discs, and the ultimate in brake fluid performance is required. Radi-CAL™ R2 replaces AP Racing’s 600 Racing Fluid.
