Purpose and Specifications

Keep your brakes responsive and safe with BOSCH Brake Fluid 1 987 479 115, a premium DOT 4 formula designed for reliable stopping power. This high-performance fluid resists boiling even under intense braking heat, staying effective up to 260°C dry and 170°C wet - perfect for daily drives, towing, or spirited performance driving.

Packaged in a sturdy 20-liter tank, it's ideal for professional shops or bulk fleet maintenance. The yellow-colored fluid flows smoothly at -40°C (max viscosity 700 mm²/s), ensuring crisp pedal feel in freezing winters while protecting against corrosion and moisture buildup for longer system life.

• High boil point: Handles extreme heat from hard stops without vapor lock or fade.
• Low-temp performance: Pumps easily in cold weather for consistent braking.
• Premium quality: BOSCH BF042 series fights acid formation to extend caliper and master cylinder life.

When to Use / Replace?

Flush your brake fluid every 2 years or 30,000-45,000 km under normal driving to prevent moisture absorption that causes spongy pedals and corrosion. For towing, track use, or hot climates, change annually or every 20,000 km. Shelf life is typically 3-5 years unopened; test fluid color and moisture if unsure - dark or contaminated fluid means replace now.

Compatible with all DOT 4 systems in cars, trucks, and motorcycles. Always bleed properly for air-free performance.
