The product consists of a mixture of polyalkylene glycol esters and boron-containing esters combined with highly effective additives and inhibitors that provide excellent protection against corrosion and prevent the formation of steam jams at high temperatures.

All normal brake fluids are destroyed during use. It is strongly recommended to change the Castrol Brake Fluid DOT 4 in accordance with the instructions of the equipment manufacturers. If there are no prescriptions, it is recommended to change the liquid every 2 years.

Terms of use:

Castrol Brake Fluid DOT 4 should not be used in brake systems where mineral-based fluids are prescribed (for example, some Citroen systems for which Castrol LHM is suitable, and Rolls Royce where Castrol HSMO Plus is approved for use).
As with all brake fluids containing glycol esters, be careful and avoid spilling this product on the painted surface, as this may damage the paint. In case of spillage, immediately flush the affected area with water. Do not wipe.
