The exceptionally high dry boiling point, (higher than 300°C) makes Castrol React SRF ideal for use under arduous braking conditions such as racing or rallying. Where the Castrol SRF fluid stands out is its stability over a long period of time. For track and road cars used regularly without servicing this is ideal as even after absorbing 3.7% water over 1-2 years its still able to cope with high demanding driving.

  • High Boiling Point
  • Very high vapour lock point and has the additional advantage of sustaining high vapour lock point characteristics during its service life.
  • It is compatible with seal rubber and metal materials used in brake systems using conventional polyglycol brake fluids.
  • It is similar in viscosity to conventional brake fluids so is easy to bleed like conventional brake fluids.
  • Miscible with all conventional fluids meeting the US Federal Standards FMVSS 116 DOT 3, DOT 4 and DOT 5.1, ISO 4925 and current SAE J1703.

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.

Exceeds US Federal Standards FMVSS 116 DOT 3 DOT 4, ISO 4925, JIS K2233 SAE J 1703 & SAE J 1704 SAE J1703 FMVSS 116 DOT 3 & 4
