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.
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.
