Purpose and Specifications

Trust Bosch DOT 4 Brake Fluid (1 987 479 112) to deliver reliable stopping power in everyday driving and demanding conditions. This premium yellow fluid resists boiling even after absorbing moisture from normal use, staying effective up to 260°C dry for sharp braking without fade and 170°C wet to handle real-world heat buildup. It flows smoothly in cold weather down to -40°C, ensuring responsive brakes when you need them most.

Packaged in a convenient 0.5-liter bottle with a 75mm diameter and 128mm height, it's easy to store and use for full system flushes. As a high-performance DOT 4 formula from Bosch's Premium line (BF039), it protects calipers, lines, and master cylinders from corrosion, extending brake life.

When to Use / Replace?

Replace brake fluid every 2 years or 30,000-45,000 km under normal driving to prevent moisture buildup that causes spongy pedals, longer stops, or corrosion. Flush sooner—at 1 year or 20,000 km—if you tow, drive in extreme heat/cold, or track your vehicle. Shelf life is typically 3-5 years unopened; always check for clarity before use. Regular changes keep your brakes firm and safe.
