Castrol React Performance Brake Fluid Dot 4 1lt 265 Degree Wet Boiling Point

Castrol React Performance Dot 4 (Formerly Response Super DOT 4) Synthetic Brake Fluid is a high boiling synthetic brake fluid which far exceeds the requirements of the SAE J1703, FMVSS 116 DOT 3 and 4, ISO 4925 and JIS K2233 specifications.
Designed for use in all brake systems particularly those which are exposed to extreme conditions. 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.
It is strongly recommended that brake fluid should be changed according to the vehicle manufacturers advice. In the absence of such advice, a 2 year change period is recommended.
