Purpose and Specifications

Bosch 1 987 479 208 is premium ENV6 brake fluid in a 5-liter canister, compatible with DOT 3, DOT 4, and DOT 5.1 systems. It delivers exceptional heat resistance with a dry boiling point over 270°C to prevent brake fade during hard stops, and a wet boiling point around 180-185°C even after absorbing moisture over time.

This yellow fluid stays fluid in extreme cold down to -40°C for reliable braking in winter, while protecting ABS and ESP systems with special lubricants for smooth operation. Its low viscosity ensures quick response in modern vehicles like Mercedes-Benz B-Class and AMG GT models from 2018 onward. Tinplate packaging offers a shelf life of at least 5 years when sealed.

When to Use / Replace?

Use Bosch ENV6 for high-performance braking in everyday or track conditions where heat builds up fast. Replace every 2 years or 40,000 km, whichever comes first, as brake fluid absorbs water and loses effectiveness. Check with a tester if boiling point drops below safe levels for your operating temps up to 150°C in heavy use.

Ideal for extended service in compatible cars, lasting up to 50% longer than standard DOT 4.
