CASTROL REACT PERFORMANCE DOT 4

High-performance brake fluid

Castrol React Performance DOT 4 brake fluid is a synthetic oil that is specifically designed to deliver superior braking at high speed, for a variety of demanding applications.


The high-performance additives in Castrol’s engine oils and lubricants help cars to drive faster, with greater efficiency, reduced wear and decreased maintenance requirements. However, driving fast is only desirable when you can trust your brakes; this means using brake fluid that is designed with the same demands in mind.


Castrol React Performance DOT 4 contains high-performance additives to deliver braking that is trusted by motorsport teams around the world. It has a higher boiling point than standard brake fluids and exceeds the high temperature requirements of the DOT 4 category requirements, meaning that it has a longer lifespan than other products on the market.


Beyond this, Catrol’s range is available in a number of different formulations to ensure they are suitable to optimise braking performance for almost every vehicle. This includes products that meet a range of DOT standards, so you can enjoy exceptional performance no matter your technical specifications.

How to get the most from your brake fluid

Brake fluid must operate at peak performance at all times to minimise the risk of accident and injury, but this is only possible when the system is maintained correctly. Brake fluid often absorbs water while in operation, and at a high enough concentration the boiling point of the fluid will be reduced. This will make your brake fluid perform less effectively, potentially lead to corrosion and other damage, and could introduce safety issues into your brake system.


If your vehicle’s brake fluid is ineffective, it may be difficult to tell until further symptoms - like increased wear or reduced reliability when driving under extreme conditions - make it apparent.


As a result, it is not only important that you select a product that is specifically designed to match your technical requirements; you must also ensure you can rely on your braking systems by checking them as often as possible. You should monitor your brake fluid every two years at a minimum, but ideally during every service of your vehicle - consult your vehicle manufacturer’s recommendations for more specific instructions.
