Karlsruhe, Germany – To raise their boiling point, conventional brake fluids contain borates. But these are classified as toxic; they can affect fertility and endanger unborn children. That’s why brake fluids have to be handled with protective gloves and goggles, and why pregnant women should avoid any contact with brake fluid. Now Bosch has developed a brake fluid called DOT 4 E that contains no hazardous borates and achieves a good balance between a high boiling point and low viscosity. Because it isn’t classified as a hazardous substance, it’s safe for pregnant women to handle. What’s more, it exceeds the international DOT 4 standard and demonstrates low viscosity. This makes it suitable for many vehicle types with ABS and ESP. In developing the new brake fluid, care was taken to ensure that it exhibits low electrical conductivity and – like all other brake fluids from Bosch – can be used in electric vehicles.
