Purpose and Specifications

Febi Bilstein 180584 is a premium fully synthetic DOT 5.1 brake fluid designed for hydraulic brake and clutch systems in modern vehicles. This high-performance fluid absorbs heat from braking up to 260°C dry boiling point and maintains reliability at 180°C even when wet, preventing dangerous vapor lock and ensuring crisp, responsive stops every time.

It meets strict standards like FMVSS 116 DOT 5.1, ISO 4925 Classes 3, 4, and 5.1, SAE J1703, and SAE J1704, with built-in oxidation and corrosion inhibitors that protect calipers, lines, and seals from rust and wear. One 1-liter bottle covers most full flushes, mixable with other DOT 5.1 fluids for easy top-ups.

When to Use / Replace?

Use Febi Bilstein 180584 in vehicles requiring DOT 5.1 specification, especially those with ABS, ESP, or high-performance brakes that run hot. Replace every 2 years or 40,000 km, whichever comes first, as brake fluid naturally absorbs moisture over time, dropping its boiling point and risking brake fade.

• Flush if pedal feels spongy or after heavy track use where temps exceed 150°C.
• Ideal for daily drivers, towing, or spirited driving to maintain safety.
• Shelf life: 3-5 years unopened in cool, dry storage.
