Purpose and Specifications

BOSCH 1 987 479 206 brake fluid is a premium DOT 3, DOT 4, and DOT 5.1 compatible fluid in a convenient 0.5-liter can. It delivers reliable braking performance by resisting boil-off up to 270°C dry for fade-free stops during hard driving and holding steady at 180°C wet even after absorbing moisture over time. The yellow formula flows smoothly at -40°C, ensuring responsive brakes in freezing weather without getting too thick.

Key practical benefits include superior heat protection for track days or towing, corrosion defense for brake components, and compatibility with most ABS and ESP systems. Shelf life is typically 3-5 years unopened when stored cool and dry.

When to Use / Replace?

Use this high-performance fluid for vehicles demanding DOT 4 or 5.1 specs, like European cars with advanced braking tech. Replace every 2 years or 40,000 km, whichever comes first, to prevent moisture buildup that lowers boiling point and causes spongy brakes. Flush completely if switching from mineral oil or DOT 5 silicone types.

• Ideal for daily drivers, performance cars, and heavy-duty use.
• Check fluid level and color yearly; dark or low means replace now.
• Operating temps: Safe up to 150°C continuous in normal traffic.
