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.

Utilizing the latest friction material technology, Race Technologies RE10 offers consistent performance in the most demanding environments. Typical applications include professional endurance racing, club racing, and HPDE on high braking demand platforms. RACING PAD NOTES: Running a "racing use only" pad on the street could produce excessive noise and dust. Rotor wear could be accelerated if driven at consistently cold temperatures or used in the incorrect temperature range. Racing pads are designed to work in specific temperature ranges so it's important to choose the right compound for the environment the vehicle will be used in. Pad compounds are tested on a brake dynamometer over repeated brake applications to test the materials in a controlled environment. Real-world wear rates and temperatures will be influenced by car setup, grip levels, track layout and other variables. Note: "RE" denotes a "racing use only" pad compound.
