Purpose and Specifications

Keep your brakes responsive and safe with BOSCH Brake Fluid 1 987 479 203, a premium DOT 4 formula in a convenient 5-liter tank. This yellow fluid delivers rock-solid braking by resisting heat buildup during hard stops, maintaining smooth pedal feel in everyday driving or demanding conditions. It flows easily in cold weather down to -40°C for quick response, while staying stable at high temperatures to prevent fade and vapor lock.

Designed for reliability, it absorbs moisture over time to protect your brake system from corrosion, ensuring consistent performance for daily commuters, towing, or spirited drives. The large 5L size is perfect for full flushes or servicing multiple vehicles.

When to Use / Replace?

Replace every 2 years or 30,000-45,000 km under normal driving to avoid spongy pedals, longer stops, or corrosion damage. Flush sooner for towing, track use, or extreme climates (annually or every 20,000 km). Shelf life is typically 3-5 years unopened; test fluid color and condition regularly for safety.

Ideal for modern cars, trucks, and motorcycles requiring DOT 4 fluid.
