Purpose and Specifications

ATE DOT 4 Brake Fluid (03.9901-5802.2) is a premium 1-liter can of high-quality SL DOT 4 fluid designed to deliver reliable braking performance in everyday and demanding driving conditions. It resists boiling even under intense heat, staying effective up to a dry boiling point of 260°C for fade-free stops during hard braking, and maintains performance above 165°C even when moisture builds up over time. This low-viscosity formula flows smoothly in cold weather for quick response, making it perfect for vehicles with ABS, ESP, and other modern systems.

Key practical benefits include superior water absorption to prevent corrosion in brake lines and components, ensuring long-term system reliability. It's fully compatible with all DOT 4 systems and meets strict standards like ISO 4925 Class 6 for consistent power.

When to Use / Replace?

Use ATE DOT 4 for passenger cars, performance vehicles, and systems requiring DOT 4 fluid - always check your owner's manual. Replace every 2 years or 40,000 km under normal driving to avoid moisture-related boiling and reduced braking efficiency. Shelf life is up to 5 years when unopened and stored properly in a cool, dry place.

Pro Tip: Flush the system completely during changes to maximize benefits and safety.

Frequently Asked Questions

• Is ATE DOT 4 safe for my ABS-equipped car? Yes, its low viscosity at cold temps ensures fast ABS activation, while high boiling points handle heat from emergency stops.
• How often should I change brake fluid? Every 2 years or 40,000 km - test boiling point annually if you drive aggressively.
• Can I mix it with other DOT 4 fluids? Yes, it's fully compatible, but for best results, use ATE throughout the system.
