Purpose and Specifications

FEBI BILSTEIN 180590 is a premium DOT 4 LV fully synthetic brake fluid designed to meet the highest safety standards for modern vehicle braking systems. This 0.5-liter bottle contains glycol-based fluid engineered to handle extreme temperatures and high-pressure braking conditions.

Key Performance Specs:

• Dry boiling point: 265°C – ensures brake fluid remains stable even during intense braking
• Wet boiling point: 170°C – maintains safety when moisture enters the system over time
• Operating temperature range: -40°C to +100°C – flows smoothly in winter cold and resists breakdown in summer heat
• Meets ISO 4925 Class 3, 4, and 6 standards – compatible with virtually all modern brake systems
• Approved for Ford, VW, SEAT, and other major manufacturers

The fluid contains corrosion inhibitors and oxidation protectors that shield internal brake components from rust and degradation. Its low viscosity ensures rapid pressure changes throughout your brake lines, giving you responsive, reliable stopping power in all driving conditions.

When to Use / Replace?

Replace your brake fluid every 2 years or 40,000 km, whichever comes first. Brake fluid absorbs moisture from the air over time, which lowers its boiling point and reduces braking performance. Even small amounts of water contamination can cause brake fade during heavy braking.

Use this product immediately if you notice:

• Soft or spongy brake pedal
• Brake warning light on your dashboard
• Reduced braking responsiveness
• Fluid that appears dark or discolored

This 0.5-liter bottle is ideal for topping up or small brake system maintenance. For a complete fluid flush, you may need multiple bottles depending on your vehicle's brake system capacity (typically 0.8–1.5 liters).

Frequently Asked Questions

Q: Can I mix this brake fluid with my current fluid?
A: Yes. FEBI DOT 4 LV is fully compatible with existing DOT 4 and DOT 4 LV fluids in your brake system. However, for best results, perform a complete fluid flush every 2 years rather than topping up with different brands.

Q: How long does an unopened bottle last?
A: Unopened brake fluid remains stable for approximately 3–5 years when stored in a cool, dry place away from direct sunlight. Once opened, use the fluid within 6 months to prevent moisture absorption.

Q: Is this fluid suitable for my older car?
A: Check your vehicle's manual or brake fluid reservoir cap for the required DOT specification. This DOT 4 LV fluid works with most cars built after 1990. Older vehicles may require DOT 3; never use a lower DOT rating than specified.
