ESI6 Extended Service Brake Fluid - 1qt (946ml)

Modern brake systems, such as those featuring ABS and ESP®, are designed for improved performance to safely stop vehicles. With improved performance comes a higher load on the braking systems. These systems require a brake fluid with a high wet boiling point, low viscosity, and high lubricity.

As a vehicle system developer and the first to market ABS and inventor of ESP®, Bosch understands the need for high-quality brake fluid.

Bosch ESI6 is a next-generation brake fluid. It exceeds all current DOT standard requirements (FMVSS 116).

Features:

• First to simultaneously combine both low viscosity and high wet boiling point at its operation
• Longer lasting: 100% longer than DOT 3, 50% longer than DOT 4, and 10% longer than DOT 5.1 (with 30% lower viscosity: -40 DegreeC ~670mm2/s)
• ESI coverage includes the majority of all brake systems launched since 1990; Use with DOT 3, DOT 4, or DOT 5.1; Coverage excludes DOT 5 silicone-based brake fluid which is limited to military and racing applications
• Excellent lubricity properties to prevent wear of components in the brake system and reduce noise

ESI6 contributes to the high performance and service life of modern brake systems with its high dynamic properties. For over two years, it has undergone sophisticated testing geared towards new versions of ABS and ESP® systems in our Bosch development center in Abstatt, Germany. ESI6 brake fluid has been subject to intense testing of both system pressure build-up and wear and noise at extreme temperatures.
