JPN DOT 4 Brake Fluid - Reliable Stopping Power for Daily Driving

Purpose and Specifications

JPN DOT 4 Brake Fluid is a polyglycol-based hydraulic fluid designed to transfer braking force from your pedal to the wheels with precision and consistency. This 500ml bottle meets DOT 4 safety standards, making it suitable for all standard passenger vehicles with disc brakes, drum brakes, and ABS systems.

Key Performance Features:

• Higher Boiling Point: Resists brake fade by maintaining performance even when brake systems heat up during normal driving, city traffic, or moderate highway use
• Moisture Protection: Formulated to resist water absorption from air, keeping your brake system clean and responsive over time
• Corrosion Resistance: Protects internal brake components from rust and wear, extending system lifespan
• Seal Compatibility: Works safely with all rubber seals and components in modern brake systems

When to Use and Replace?

Use JPN DOT 4 for everyday commuting, city driving, and moderate highway use where brake temperatures stay moderate. This fluid is ideal for vehicles without extreme towing loads or mountain driving demands.

Replacement Schedule: Change your brake fluid every 2 years or 40,000 kilometers, whichever comes first. If you notice soft or spongy brake pedal feel, or if your vehicle has been in storage, flush and replace immediately. Budget-class fluids like JPN DOT 4 absorb moisture faster than premium alternatives, so regular maintenance is important for safety.

Operating Temperature Range: Maintains performance between -40°C and +260°C, covering all normal driving conditions.

Shelf Life: Store in a cool, dry place. Unopened bottles remain effective for 3-5 years. Once opened, use within 6 months to prevent moisture contamination.

Frequently Asked Questions

Q: Can I mix JPN DOT 4 with other DOT 4 brands?
A: Yes. DOT 4 fluids from different manufacturers are compatible with each other. However, avoid mixing with DOT 3 or DOT 5 fluids, as they have different chemical properties.

Q: Is DOT 4 suitable for my vehicle?
A: Check your vehicle's owner manual for the recommended brake fluid type. DOT 4 works in most modern cars, SUVs, and light trucks. If your manual specifies DOT 3, DOT 4 can be used as an upgrade. If it specifies DOT 5.1, use that instead for better heat resistance.

Q: Why does my brake fluid need changing if it looks clean?
A: Brake fluid absorbs moisture from the air even in sealed systems. This water lowers the boiling point and can cause brake fade or corrosion inside your brake lines. Regular changes prevent these hidden problems.
