Purpose and Specifications

ATE SecuBrake DOT 4 brake fluid (03.9901-6803.2) is a premium 5-liter can designed for reliable braking in cars, motorcycles, and electric vehicles. Made from over 80% renewable resources without boric acid esters, it offers top safety with a dry boiling point over 260°C to prevent vapor lock during hard stops and a wet boiling point above 155°C for consistent performance even when moisture builds up. Its low viscosity at -40°C ensures smooth flow in cold weather, making it perfect for ABS, ESP, and modern systems.

This sustainable fluid protects against corrosion, resists aging, and is readily biodegradable with a smaller carbon footprint. It's compatible with DOT 3, DOT 4, and DOT 5.1 fluids, simplifying top-ups or flushes. No hazardous labeling means easier workshop handling and storage.

When to Use / Replace?

Use ATE SecuBrake for everyday driving, high-performance needs, or eco-friendly upgrades. Ideal replacement every 2 years or 40,000 km to maintain braking power, as brake fluid absorbs moisture over time, dropping its boiling point and risking brake fade. Check fluid color - dark or cloudy means replace now. Shelf life is 5 years unopened when stored cool and dry.

Key Benefits:

• Stays effective from -40°C to over 260°C for all-weather reliability
• Corrosion protection extends brake system life
• Sustainable choice without compromising DOT 4 performance
• Quick response in ABS/ESP systems
