Purpose and Specifications

VALEO 402406 is a premium synthetic DOT 4+ brake fluid in a 1-liter bottle, designed to deliver reliable braking power for everyday and performance driving. It resists boiling up to 265°C dry, preventing brake fade during hard stops or high-heat conditions like mountain descents or spirited drives, keeping your brakes responsive when you need them most.

This mid-range fluid meets strict specs from brands like Fiat, VW, Peugeot, Citroën, Chrysler, Daimler, MAN, Nissan, Hyundai, Kia, and Renault, making it a versatile choice for many European and Asian vehicles. Its synthetic formula absorbs less moisture than standard fluids, maintaining consistent performance and protecting calipers, lines, and master cylinders from corrosion.

When to Use / Replace?

• Replace every 2 years or 40,000 km: Brake fluid is hygroscopic (absorbs water from air), which lowers its boiling point over time and risks spongy brakes or failure.
• Use in operating temps from -40°C to over 200°C: Flows smoothly in winter cold for quick response, stays stable in summer heat or track use.
• Shelf life: 3-5 years unopened: Store sealed in a cool, dry place; once opened, use within months.

Ideal for flush-and-fill during routine service to ensure sharp, safe stopping power.

FAQ

Q: Is VALEO 402406 compatible with my DOT 4 system?
A: Yes, its DOT 4+ rating is backward-compatible with DOT 4 systems and approved for major OEM specs—check your owner's manual.

Q: Can I mix it with older brake fluid?
A: Top up in emergencies only; for best results, fully flush the system to avoid moisture buildup and performance loss.

Q: How do I know when it's time to change?
A: Test boiling point at a shop or change proactively every 2 years/40,000 km—darkened or contaminated fluid means replace now.
