Febi Bilstein 21754 DOT 4 Brake Fluid - Reliable Stopping Power for Your Vehicle

Purpose and Specifications

Febi Bilstein 21754 is a premium synthetic DOT 4 brake fluid in a convenient 5-liter canister, weighing 5.6 kg. It delivers smooth, responsive braking by transferring hydraulic pressure efficiently from pedal to brakes, while protecting against corrosion and oxidation for longer system life.

• High-heat performance: Stays effective up to 260°C dry boiling point, preventing brake fade during hard stops or downhill driving in hot conditions (over 100°C).
• Moisture-resistant: Maintains braking power at 160°C even after absorbing water over time, outperforming basic DOT 3 fluids.
• Wide compatibility: Meets VW TL 7766, Ford SAM 6C9103 A, Renault 41-02-001, GM, and SAE J1703 specs - ideal for European cars like VW, Audi, Ford, Opel, and more.

Practical perks: Ensures firm pedal feel, reduces sponginess, and extends caliper/piston life. Shelf life is 3-5 years unopened; store cool and dry.

When to Use / Replace?

Use for flush/replace every 2 years or 40,000 km - whichever comes first - as moisture buildup lowers performance after 24-36 months. Replace immediately if brakes feel soft, during ABS/TCU service, or if fluid looks dark/contaminated. Perfect for high-performance driving where temps exceed 150°C.

FAQ

Can I mix this with my old DOT 3 fluid? No - always fully flush the system to avoid reduced boiling point and corrosion risks.

Is it safe for daily drivers or track use? Yes, handles everyday commuting up to spirited/track sessions without fading.

How much for a full brake flush? Typically 1-2 liters for most cars; this 5L canister covers multiple vehicles or spares.
