Purpose and Specifications

Keep your brakes responsive and safe with Bosch DOT 4 HP Brake Fluid (1L), a high-performance formula designed for modern vehicles with ABS and ESP systems. This low-viscosity fluid flows quickly even at -40°C, ensuring fast ABS response in cold weather for shorter stopping distances. It resists boiling up to 260°C dry and 170°C wet, preventing brake fade during hard stops or track days when temps exceed 150°C.

Practical perks include smoother pressure build-up for confident braking, compatibility with all DOT 4 systems, and extended service life versus standard fluids. Yellow-colored for easy identification, it comes in a durable 94mm diameter bottle (151mm height) that's easy to store and pour.

When to Use / Replace?

Use this premium fluid in cars, trucks, or motorcycles with electronic brakes built since 1990. Ideal for high-performance driving, towing, or cold climates where standard DOT 4 might sluggish up. Replace every 2 years or 40,000 km, whichever comes first, as it absorbs moisture over time, dropping performance and risking corrosion. Shelf life is 5 years unopened.

• Flush if brakes feel spongy or pedal sinks.
• Perfect upgrade for European vehicles requiring low-viscosity DOT 4.
• Never mix with DOT 5 silicone fluids.
