Febi Bilstein 180591 DOT 5.1 Brake Fluid - Reliable Stopping Power for Your Vehicle

Purpose and Specifications

Febi Bilstein 180591 is premium DOT 5.1 brake fluid in a convenient 5-liter size, designed to deliver smooth, responsive braking even under intense heat. This glycol-based fluid resists boiling during hard stops, staying effective up to 260°C in dry conditions and 180°C when wet, so your brakes perform consistently without fading on highways or spirited drives.

It meets top standards like FMVSS 116 DOT 5.1, ISO 4925 Classes 3, 4, and 5.1, plus SAE J1703 and J1704, making it ideal for modern cars, trucks, and performance vehicles needing dependable hydraulic power.

• Key Benefits: Prevents vapor lock for firm pedal feel, fights moisture to reduce corrosion, and protects master cylinders and calipers from wear.
• Shelf Life: Up to 2 years unopened for fresh performance when you need it.
• Net Weight: 0.296 kg per unit - lightweight yet packed with protection.

When to Use / Replace?

Use Febi Bilstein 180591 for full flushes during brake jobs or routine maintenance. Replace every 2-3 years or 30,000-45,000 km for daily drivers to keep fluid fresh and brakes sharp - check sooner if you track your car or drive aggressively, as heat speeds up degradation.

Operating temps up to 260°C dry handle hot summer stops or towing; wet performance at 180°C suits rainy conditions without losing grip.
