Purpose and Specifications

Febi Bilstein 180592 is a premium fully synthetic DOT 5.1 brake fluid designed for hydraulic brake and clutch systems in modern vehicles, including electric and hybrid models like Tesla. This high-performance fluid absorbs heat from braking up to 274°C dry and maintains reliability at 184°C wet, preventing vapor lock and brake fade during intense stops. It fights corrosion, lubricates components for smooth operation, and mixes safely with other glycol-based synthetics.

Supplied in a 5-liter recyclable polyethylene bottle with easy-grip handle and level strip, it's perfect for full flushes or workshop use. Meets strict standards like FMVSS 116 DOT 5.1, ISO 4925 Classes 3-6, SAE J1703/1704 for OE-quality safety.

When to Use / Replace?

Use this fluid for vehicles requiring DOT 5.1 specs, especially high-performance cars, trucks, or EVs with advanced ABS/ESP systems. Replace every 2 years or 40,000 km - brake fluid absorbs moisture over time, dropping performance and risking corrosion. Check if brakes feel spongy, pedal sinks, or during routine service. Shelf life is 3-5 years unopened in cool storage; always flush old fluid before adding new to avoid mixing issues.

• Ideal for temps from -40°C to over 200°C in heavy use
• Prevents costly repairs by protecting seals and pumps
• Ensures every stop counts in emergencies

FAQ

Can I mix this with DOT 4 fluid? Yes, it's compatible with other synthetic glycol fluids, but for best results, fully flush the system.

Is it safe for my hybrid or EV? Absolutely - this DOT 5.1 EHV formula is tailored for electric and hybrid vehicles with sensitive electronics.

How do I know when to change brake fluid? Test boiling point or moisture content annually; replace if over 3% water or every 2 years/40,000 km for safety.
