Castrol React Performance Dot 4 (Formerly Response Super DOT 4) Synthetic Brake Fluid is designed for use in all brake systems particularly those which are exposed to extreme conditions.

All conventional brake fluids deteriorate during use.
It is strongly recommended that Castrol React Performance Dot 4 (Formerly Response Super DOT 4) Synthetic Brake Fluid should be changed according to the vehicle manufacturers advice. In the absence of such advice, a 2 year change period is recommended.
