Castrol SRF Synthetic Racing Brake Fluid, DOT 4, 1L or 33.8 oz Bottle

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.
