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.
