The 420CNY/ barrel (16KG) brake fluid is the liquid medium that transmits the brake pressure in the hydraulic brake system. It is used in the vehicles with hydraulic brake system. Brake Fluid, also known as Brake oil or force oil, its English name is Brake Fluid, is an indispensable part of the braking system, and in the braking system, it is as a force transfer medium, because the liquid can not be compressed, so the pressure output from the total pump will be directly transferred to the sub-pump through the Brake Fluid. This product is used in the braking system of automobiles (all motor vehicles) and the hydraulic system of mechanical equipment. 1. Good viscosity-temperature property, low freezing point, good low temperature fluidity; 2, high boiling point, high temperature does not produce gas resistance; 3, the use of the process of quality change is small, does not cause metal and rubber parts of the corrosion and deterioration.
