The racers choice, a brake fluid specifically developed for auto sport applications where extreme braking conditions are encountered.

Castrol SRF is the ultimate racing brake fluid. Its unique silicon ester technology absorbs less water than conventional glycol ether fluids and prevents the fluid's high-temperature performance from deteriorating. It's high boiling point (518 degrees wet, 590 degree dry), allowing it to withstand extreme temperatures and with the superior resistance to the effects of absorbed water have established Castrol SRF Brake Fluid as the world's premier fluid for the hydraulic brakes used in all forms of motorsport and racing. SRF brake fluid can make the critical difference when using metallic brake pads with high thermal conductivity. Resistance to foaming makes it an excellent choice for use with ABS braking systems. Castrol SRF Racing Brake Fluid is packaged in easy-pour 1 liter plastic bottles.
