Purpose and Specifications

Experience reliable stopping power with Bosch DOT 4 HP Brake Fluid (1 987 479 114), a premium 5-liter canister designed for modern vehicles. This high-performance fluid excels in extreme conditions, resisting vapor lock up to 260°C dry and 170°C wet boiling points for consistent braking during hard stops or track days. Its low viscosity at -40°C (under 700 mm²/s) ensures quick ABS and ESP response even in freezing weather, flowing smoothly without sluggishness.

Key practical benefits include superior corrosion protection for brake components, extending system life, and compatibility with all DOT 4, DOT 3, and DOT 5.1 systems (never mix with DOT 5 silicone). Ideal for cars with electronic stability control, it outperforms standard DOT 4 by providing faster control cycles and thermal stability under heat.

• Volume: 5 liters - perfect for full flushes or workshops
• Color: Yellow for easy identification
• Shelf life: Up to 5 years unopened; replace every 2-3 years in use
• Operating temps: Reliable from -40°C to over 170°C wet

When to Use / Replace?

Use Bosch DOT 4 HP in vehicles with ABS, ESP, or high-performance brakes for optimal safety. Replace every 2 years or 40,000 km to prevent moisture buildup that lowers boiling point and causes spongy pedals or corrosion. Check fluid color - dark or contaminated means immediate flush. Perfect upgrade for European cars, daily drivers, or spirited road use.
