Dot 4 Brake fluid is an essential part of your car's brake system. Castrol Dot 4 brake fluid is liquid engineered to prevent vapor lock and protect your brake system.
Brakes are essential for any car and this makes brake fluid one of your car's most essential components. It has to resist the moisture that can cause vapour lock brake failure, protect against corrosion, and withstand high brake temperatures.
Choosing the right brake fluid for your car’s requirements and changing it on time is critical to safety. Castrol’s brake fluid range includes products for high performance cars, driving under demanding conditions, to products with increased safety margin.
Specifically designed to supersede high temperature requirements of DOT 4 specifications.
NB: It should not be used in braking systems where a mineral oil based fluid is recommended.
