Purpose and Specifications

BOSCH BF031 DOT 3 Brake Fluid (1 987 479 101) is a premium yellow brake fluid designed to deliver reliable braking performance in everyday vehicles. This 1-liter bottle ensures smooth hydraulic operation by resisting boil-off during hard stops, staying fluid in freezing cold down to -40°C, and protecting against corrosion in your brake system.

• High heat resistance: Handles dry temps up to 205°C and wet temps up to 140°C - prevents vapor lock and brake fade on hot days or spirited drives.
• Cold weather flow: Flows easily at -40°C for responsive braking even in winter.
• Long shelf life: Up to 3-5 years unopened when stored cool and dry.

When to Use / Replace?

Use BOSCH BF031 in any DOT 3 compatible system for cars, motorcycles, and light trucks. Replace every 2 years or 40,000 km to maintain peak performance, as brake fluid absorbs moisture over time, lowering its boiling point and risking spongy brakes.

Pro tip: Flush if brakes feel soft, during brake jobs, or if fluid looks dark - fresh fluid restores firm pedal feel and safety.
