Purpose and Specifications

Febi Bilstein 26746 is a premium fully-synthetic DOT 4 brake fluid designed for hydraulic brake and clutch systems in cars and light trucks. This 0.25-liter bottle delivers reliable stopping power by resisting heat buildup, preventing brake fade during hard stops or high-speed driving.

It fights corrosion and oxidation to keep your brake components clean and long-lasting, and mixes easily with other DOT 4 or DOT 3 glycol-based fluids. With a dry boiling point over 260°C, it stays effective in extreme heat like track days or mountain descents, while the wet boiling point above 160°C handles moisture absorption over time without losing performance.

• Practical benefits: Smooth pedal feel, no spongy brakes, protects calipers and master cylinders from rust.
• Approved for: VW, Renault, Ford, GM, and meets SAE J1703, FMVSS 116 DOT 4 standards.
• Shelf life: Up to 5 years unopened in cool, dry storage.

When to Use / Replace?

Use Febi Bilstein 26746 for routine flushes or top-ups in DOT 4 systems. Replace every 2 years or 40,000 km, whichever comes first, as brake fluid absorbs water and drops performance below 160°C wet boiling point. Signs it's time: soft brake pedal, darker fluid color, or during brake pad/rotor service.

Ideal for daily drivers facing temps from -40°C to over 200°C in brakes, ensuring safe stops year-round.
