Purpose and Specifications

ATE 03.9901-6402.2 is premium DOT 4 brake fluid in a 1-liter can, perfect for reliable braking in modern vehicles with ABS, ESP, and ASR systems. This SL.6 DOT 4 formula handles extreme heat up to 265°C dry boiling point and stays effective at 175°C wet boiling point even after absorbing moisture, preventing brake fade during hard stops or track days.

It flows smoothly in cold weather down to -40°C with low viscosity for quick ABS response, while premium additives fight corrosion and keep your brake system clean. Multilingual labels support 13 languages for global use. Shelf life is typically 3-5 years unopened; always store sealed in a cool, dry place.

When to Use / Replace?

Use ATE SL.6 DOT 4 in any vehicle specifying DOT 4 fluid, especially those with advanced safety systems needing fast, low-temp response. Replace every 2 years or 40,000 km per manufacturer guidelines to maintain braking power, as fluid absorbs water over time, dropping performance.

Flush if brakes feel spongy, pedal sinks, or during routine service. Compatible with DOT 3/4/5.1 systems but mix only with same DOT class.

FAQ

Q: Can I use this in my daily driver with ABS?
A: Yes, its low viscosity ensures lightning-fast ABS activation even in freezing temps, ideal for safety features.

Q: How often should I change brake fluid?
A: Every 2 years or 40,000 km to avoid moisture buildup that lowers boiling point and risks brake failure.

Q: Is it safe for racing or high-performance cars?
A: Absolutely, high boiling points resist fade under repeated hard braking, but follow OEM specs and change more frequently.
