Brakes are essential for any car as it is not possible to stop without them. Choosing the right brake fluid for your carís requirements and changing it on time is critical to safety. Castrolís brake fluid range includes products for high performance cars, driving under demanding conditions, to products with increased safety margin.
CASTROL REACT PERFORMANCE DOT 4 (PREVIOUSLY KNOWN AS RESPONSE SUPER DOT 4)
For high performance vehicles and race conditions.
Specifically designed to be a high temperature alternative to DOT 5.1. fluids

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.
Castrol React 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.
Conditions of Use
Castrol React Performance DOT 4 brake fluid should not be used in braking systems for which a mineral oil based fluid is recommended (for
example, some Citroen systems, for which Castrol LHM is suitable and Rolls Royce systems, for which Castrol HSMO Plus is approved).
As with all brake fluids which contain glycol ethers, care should be taken to avoid spilling this product on paintwork, as it may have a
damaging effect. In case of spillage, rinse the affected area with water immediately: Do not wipe.
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 60įC, exposed to hot sun or freezing conditions.
