Castrol React Performance DOT 4 is a high boiling synthetic brake fluid which far exceeds the requirements of the SAE J1704, FMVSS 116 DOT 3 and DOT 4, ISO 4925 and JIS K2233 specifications. This product has been formulated from mixed polyalkylene glycol ethers and borate ester together with other high performance additives and inhibitors which give ultimate system protection against the effects of corrosion and high temperature vapour lock.
Castrol React Performance DOT 4 brake fluid is designed for use in all brake systems particularly those which are exposed to extreme
conditions such as high performance vehicles and race conditions.
Castrol React Performance DOT 4 brake fluid has been specifically designed to be a high temperature alternative to DOT 5.1 fluids. Its
superior characteristics give added benefit in situations where extreme conditions are encountered and ultimate braking response required.
Castrol React Performance DOT 4 brake fluid is based on glycol ether and borate ester technology and as such has a high vapour lock point (measurement relating to high temperature performance under braking conditions). Because of the nature of this formulation, the vapour lock point can be sustained at a higher level than conventional glycol ether based fluids during the service life of the product.
CastrolReact Performance DOT 4 brake fluid is specially engineered to cater for continuous start stop braking under city driving conditions, fast driving and hilly terrain where higher brake temperatures can be generated.
It is fully compatible with other fluids meeting FMVSS 116 DOT 3, DOT 4 and DOT 5.1 – however, in order to maintain the superior
performance characteristics of Castrol React Performance DOT4 avoid mixing with other brake fluid products.
All conventional brake fluids deteriorate during use.
It is strongly recommended that Castrol React Performance DOT 4 should be changed according to the vehicle manufacturers advice. In the absence of such advice, a 2 year change period is recommended.
