Castrol React SRF Racing Brake Fluid
Ultra-High Wet Boiling Point Makes Castrol SRF A Standout
Castrol React SRF Racing Brake Fluid is an ultra-high performance brake fluid popular with many of the highest performing auto racing teams around the world. The key to Castrol SRF brake fluid's performance is its silicon-ester technology. Not only is it less hygroscopic (i.e., it absorbs less water) than typical glycol-based brake fluids, Castrol SRF also reacts chemically with any absorbed water to further reduce its adverse effects on high-temperature braking performance.
The result is an almost unheard of 518° F (270° C) wet boiling point, more than 100° F higher than most other racing brake fluids!
Exceeds SAE 1703, ISO 4925, JIS K2233, FMVSS No. 116 DOT3 and DOT 4 specifications.
Note: Castrol SRF is not a silicone-based brake fluid (i.e., DOT 5) and is compatible with most factory brake systems and fluids, including DOT 3 and DOT 4 fluids. Always follow vehicle manufacturer's recommendations when adding brake fluid.

AP Racing Radi-CAL R4 Racing Brake Fluid
Among the Highest Dry Boilings Point On The Market Today
AP Racing Radi-CAL R4 racing brake fluid has an ultra-high typical dry boiling point, at 644º F / 340º C. Radi-CAL R4 racing brake fluid has been designed to perform better than any other product at the extremes of heavy-duty braking in top levels of professional racing.
AP Racing Radi-CAL R4 has outstanding resistance to vapor lock and pedal fade under the most exacting conditions. A higher vapor lock point means a firmer brake pedal at the extremes of brake temperatures. Enhanced lubricity means R4 is a better lubricant than other market-leading racing brake fluids. This helps extend the life of the metal moving parts in your brake system while increasing system efficiency.
Radi-CAL R4 can be mixed with other DOT 3 and DOT 4 racing brake fluid, although for maximum performance your braking system should be thoroughly purged with R4 fluid.
