Castrol React SRF Synthetic Racing Brake Fluid - Competition Motorsport
Castrol Castrol React SRF Synthetic Racing Brake Fluid $74.95
Castrol React SRF Racing Brake Fluid 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 superior 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 (e.g., DOT 5) and is compatible with most factory brake systems and fluids.  Always follow vehicle manufacturer's recommendations when adding brake fluid. TYPICAL PROPERTIES: Dry Boiling Point: 590°F (310°C) Wet Boiling Point: 518°F (270°C) Superior anti-vapor lock properties One-liter (1000ml) bottle
