Ferodo FBX500B DOT 4 Synthetic Brake Fluid – Premium Protection for Your Vehicle

Purpose and Specifications

Ferodo FBX500B is a premium DOT 4 synthetic brake fluid designed for everyday driving in cars and motorcycles. This 5-liter bottle provides reliable hydraulic pressure transfer from your brake pedal to the wheels, ensuring consistent stopping power in normal road conditions.

Key Performance Features:

• High boiling point (240°C dry / 159°C wet): Prevents brake fluid from boiling and losing pressure during hard braking or extended downhill driving
• Synthetic formulation: Resists moisture absorption better than conventional fluids, maintaining brake performance over time
• Wide temperature range: Works reliably from cold winter starts to hot summer driving
• Corrosion protection: Contains additives that protect metal brake components from rust and wear
• Smooth operation: Optimized viscosity ensures easy brake bleeding and responsive pedal feel

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 effectiveness. Signs you need a fluid change include a soft or spongy brake pedal, longer stopping distances, or fluid that appears dark or cloudy.

This fluid is suitable for vehicles with standard braking systems, including those with ABS. Always follow your vehicle manufacturer's recommendations and bleed the system thoroughly when replacing old fluid.

Storage: Keep the bottle tightly sealed in a cool, dry place. Unopened fluid maintains quality for approximately 3-5 years.

Frequently Asked Questions

Q: Can I mix Ferodo FBX500B with other brake fluids?
A: No. Always use the same brake fluid type throughout your system. Mixing different fluids can reduce braking performance and damage seals. If switching brands or types, flush the entire system with the new fluid.

Q: Why does my brake fluid need replacing if it looks clean?
A: Brake fluid absorbs moisture invisibly from the air. Even clean-looking fluid loses its boiling point protection over time, which can cause brake fade during hard braking. Regular replacement prevents this hidden degradation.

Q: Is this fluid safe for racing or track use?
A: FBX500B is designed for street and normal driving. For racing or extreme track conditions, Ferodo offers specialized racing fluids with higher boiling points (330°C+) that provide better protection under sustained high temperatures.
