Purpose and Specifications

VALEO 402407 is a high-performance synthetic DOT 5.1 brake fluid in a convenient 0.5-liter bottle, perfect for maintaining reliable braking in everyday and demanding drives. It delivers superior heat resistance up to 265°C dry boiling point, preventing brake fade during hard stops or high-speed braking, while protecting your system against corrosion for longer component life.

• Optimal braking power: Ensures smooth, responsive pedal feel even under heat stress.
• Corrosion protection: Shields calipers, cylinders, and lines from rust and wear.
• Synthetic formula: Fully compatible with DOT 5.1 systems, mixes with most modern brake fluids.
• Mid-range quality: Trusted Valeo engineering at an affordable price.

When to Use / Replace?

Use VALEO 402407 for vehicles requiring DOT 5.1 fluid, like many European cars from Audi, Volkswagen, Hyundai, Kia, and more. Replace every 2 years or 40,000 km, whichever comes first, or sooner if brakes feel spongy, pedal sinks, or during ABS/ESC system flushes. Ideal for operating temps from -40°C to over 200°C in heavy use. Shelf life is 3-5 years unopened in cool, dry storage.

FAQ

Q: Is this fluid compatible with my DOT 4 system?
A: No, DOT 5.1 is glycol-based like DOT 4 but use only if your manual specifies DOT 5.1 for higher heat tolerance.

Q: How much fluid for a full brake flush?
A: Typically 1-1.5 liters for most cars; this 0.5L bottle is great for top-ups or smaller jobs.

Q: Does it work in high-performance braking?
A: Yes, its high boiling point resists vapor lock, keeping brakes firm during track days or towing.
