Racing Brake Fluid
Castrol React SRF Racing 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 meets US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925, JASO JIS K2233 and current SAE J 1703 specifications.
Castrol React SRF Racing has an exceptionally high dry boiling point, typically 325°C, making it ideal for use under arduous braking conditions such as racing or rallying.
Castrol React SRF Racing 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.
In order 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 in order to derive maximum benefit the use of Castrol React SRF Racing should be restricted to not more than eighteen months before draining and refilling.
Castrol React SRF Racing is suitable for all disc and drum brake systems with the exception of 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. However, 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 it's exceptionally high vapour lock performance.
