Purpose and Specifications

Febi Bilstein 180586 is premium DOT 5.1 brake fluid that keeps your brakes responsive and safe under extreme heat. This fully synthetic fluid resists boiling even after absorbing moisture, staying effective up to 100°C operating temps in daily driving and much higher during hard stops. It protects against corrosion, lubricates seals for smooth caliper action, and flows easily in cold weather down to -40°C for quick braking response.

Packaged in a 0.5-liter eco-friendly, leak-proof bottle with easy-grip handle and fill-level strip, it's a direct OE match for European and Asian vehicles including Tesla models.

When to Use / Replace?

Use Febi 180586 for vehicles requiring DOT 5.1 specs, especially high-performance or ABS systems where low viscosity ensures fast pressure build-up. Replace every 2 years or 40,000 km, or sooner if fluid darkens or you notice spongy brakes - moisture lowers boiling point over time, risking vapor lock above 184°C wet. Shelf life is 3-5 years unopened in cool storage.

• Ideal for track days or towing: Handles temps beyond standard DOT 4.
• Mixes with DOT 4/5.1 but flush system for best results.
• Prevents seal swelling/shrinking for leak-free performance.

FAQ

Can I mix this with DOT 4 fluid? Yes, it's compatible, but for peak performance, fully flush the old fluid to avoid lowering the boiling point.

How do I know when to change brake fluid? Check every 2 years or 40,000 km; test boiling point at a shop or look for discoloration/moisture absorption signs.

Is it safe for ABS and ESP systems? Absolutely, meets ISO 4925 Class 6 for low viscosity and high-pressure compatibility in modern brakes.
