AP Radi-Cal™ R4 Brake Fluid

$39.95

AP Racing offers the perfect brake fluid for your car, regardless of whether you're chasing groceries or lap times.The AP formulations below have been refined over many years under the most arduous conditions encountered at the highest levels of motorsport.These fluids are some of the most popular used today in Formula 1, NASCAR Sprint Cup, WRC, ALMS, etc. All AP Racing Brake Fluids with the exception of R4 are compatible with all hydraulic brake systems designed to conform to S.A.E. J1703 requirements, which means they're just at home on the road as they are on the track.

Following the successful launch of Radi-CAL™ R4 racing fluid in 2014, AP Racing chose to change the packaging and names of all of its fluid options to create uniformity across the line. NO alterations have been made to the actual fluids themselves, and the former product names are listed below.
