Bosch ENV6 Brake Fluid: Developed to Cope with the High Strains Caused by Modern and Future Brake Systems

Particularly reliable and safe thanks to its low viscosity and its high wet boiling point

  • High-performance brake fluid for almost any brake system launched since 1990
  • Shorter ESP® reaction times, reduced formation of vapor bubbles
  • Reduced stock-keeping efforts and requirements thanks to its downward compatibility, its long shelf live and the fact that it is not classified as a dangerous substance

The performance of modern brake systems is continuously improved while the reaction times of ABS and ESP® are getting faster and faster. In addition, modern cars are more and more often equipped with driver assistance and driving safety systems with additional functions, too. In future, the dynamic pressure build-up of emergency brake assists will, for instance, be one of the factors deciding about the vehicle’s safety performance assessment (NCAP). As a developer of modern vehicle safety systems, Bosch also focuses on the brake fluids used. By means of ENV6, Bosch provides a particularly powerful and reliable brake fluid meeting the growing demands of modern and future brake systems. The name “ENV” is derived from the English term “envelope”. It points out the high-performance brake fluid’s suitability for practically any brake system launched since 1990.

Unique combination of characteristics: low viscosity and high wet boiling point

ENV6 stands out for being the first brake fluid ever developed to combine both a very low viscosity – i.e. very high fluidity – and a very high wet boiling point in comparison with conventional brake fluids. The lower the viscosity, the shorter the reaction times of ESP® systems, for instance. The high wet boiling point reduces the risk of formation of vapor bubbles – the main cause of brake failure. So far, this combination of both of these features is absolutely unique. It makes ENV6 particularly reliable and safe. As a result, ENV6 can be used to replace several different brake fluids such as DOT3, DOT4 or DOT5.1. Very rarely used brake fluids based on mineral oils (LHM) or containing silicones (DOT5) are the only ones not compatible.

Significantly increased replacement intervals

Thanks to its very good technical characteristics, the replacement intervals of the high-performance brake fluid were significantly increased as well. While standard DOT4 brake fluids need to be replaced every two years, the ENV6 replacement interval comprises three years. Its high lubricity prevents noises and protects the brake system against wear and corrosion.

At the workshop, ENV6 can thus be used to replace several different conventional brake fluids. This reduces the risk of filling the brake system with inappropriate brake fluids or mixing different ones. It also reduces the required storage space at the workshops. Bosch supplies ENV6 in 1.0-, 5.0 and soon also in 20.0-liter cans allowing it to be used for up to five years as long as the cans remain unopened. On top of that, its stock-keeping at the workshop is eased even further by the fact that it is not classified as a dangerous substance as specified by the Ordinance on Hazardous Substances.
