Brake fluid Dot 4 React Performance

Castrol React Performance DOT 4 is a specific brake fluid designed to be an alternative to DOT 5.1 fluids used in high temperatures.
The improved characteristics of this brake fluid come into their own in extreme operating conditions and when immediate braking system response is essential.
Adapted to the demands of urban driving, rapide or mountainous regions, where braking systems are subjected to high thermal stress.
Designed for use in all types of braking systems operating under the most severe conditions, even in sports use.

This product has been formulated from a blend of polyakene glycol ethers and borate esters, high-performance additives and inhibitors that provide absolute protection against the effects of corrosion and the formation of vapor buffers at high temperatures.

High-boiling synthetic brake fluid point which far exceeds SAE J1704, FMVSS 116 DOT 3 and DOT 4, ISO 4925 and JIS K2233 performance levels.
Kinematic viscosity at -40°C = 1200 mm²/s (IP71 method)
Density at 20°C = 1.07 g/ml (IP160 method)
