Castrol React SRF Racing brake fluid is a high performance brake fluid of special value in competitive motor sport where extreme braking conditions are encountered. It is an exclusive Castrol product registered under patents in many countries. Castrol React SRF Racing exceeds US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925, JIS K2233 and current SAE J 1703 specifications.
Castrol React SRF has been especially formulated to maximise braking performance under arduous competitive conditions. In order to achieve the optimum benefits in such applications, advanced materials have been employed in a unique and patented Castrol formulation. The use of Castrol React SRF should be restricted to not more than eighteen months before draining and refilling for maximum efficiency. Prolonged use in excess of the recommended period may give rise to a deterioration in performance at very low temperatures. Castrol SRF is suitable for all disc and drum brake systems with the exception of those for which mineral oil is prescribed.
The racing brake fluid! The high boiling point (518 degrees wet, 590 degrees dry) exceeds DOT 4 specifications. 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.
