Castrol React SRF Racing Brake Fluid
Castrol React SRF Racing is a high-performance brake fluid of special value in competitive motor sports 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 Racing is suitable for all disc and drum brake systems except those for which mineral oil is prescribed. It is miscible with all conventional fluids meeting US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925 and current SAE J 1703 and J1704.
owever, mixing with conventional brake fluids will merely reduce the higher quality of Castrol React SRF Racing and therefore recommended that conventional brake fluids be drained from the system before flushing and re refilling.
It is recommended that this fluid is changed every 18 months to maintain its exceptionally high vapour lock performance
Castrol React SRF Racing has an exceptionally high dry boiling point ( typically 320°C ) making it ideal for use under arduous braking conditions such as racing or rallying. React SRF has a very high vapour lock point (the more important measure of high-temperature performance under actual braking conditions), and has the additional advantage of sustaining high vapour lock point characteristics during its service life.
To achieve the optimum benefits in such applications, advanced materials have been employed in a unique and patented Castrol formulation. The properties of this formulation are such that to derive maximum benefit, the lifespan of this product should be restricted to not more than eighteen months before draining and refilling.

Storage
All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and the obliteration of drum markings. Products should not be stored above 60°C, or exposed to hot sun or freezing conditions.
