Purpose and Specifications

ATE SUPER DOT 5.1 brake fluid (03.9901-6602.2) is a premium synthetic formula in a 1-liter can, meeting DOT 5.1 standards for reliable braking in modern vehicles. It delivers top performance in extreme heat and cold, with a very high wet boiling point over 180°C to prevent vapor lock during hard stops, and low viscosity for quick response even in freezing temps.

This fluid excels in cars with advanced systems like ESP, ABS, and ASR, offering fast reaction times, corrosion protection, and smooth pedal feel. Multilingual labels support global use, from English to Thai.

When to Use / Replace?

Use ATE SUPER DOT 5.1 for vehicles requiring DOT 5.1 fluid, especially those with electronic stability control or high-performance demands. Replace every 2 years or 40,000 km to maintain braking power, as moisture absorption lowers boiling point over time. Shelf life is 3-5 years unopened; check vehicle manual for exact intervals.

Key Benefits:

• Stays effective above 180°C wet to avoid brake fade on long descents
• Flows fast in cold weather for instant ABS activation
• Protects seals and components from rust and wear
• Compatible with DOT 4 systems for easy upgrades
