Purpose and Specifications

The JPN JPN-DOT4 1L brake fluid is a budget-friendly DOT 4 solution perfect for keeping your car's brakes responsive and safe. This 1-liter bottle delivers high-temperature resistance to prevent brake fade during tough drives like stop-and-go traffic or hilly roads, ensuring firm pedal feel when you need it most. It absorbs moisture to fight corrosion in calipers and master cylinders, protects rubber seals from leaks, and offers smooth lubrication for all brake parts. Ideal for everyday cars, trucks, and motorcycles with hydraulic brakes or clutches specifying DOT 4.

• Works reliably up to 260°C dry boiling point and over 170°C wet for heavy braking without vapor lock
• Compatible with DOT 3 systems for easy top-ups
• Shelf life of 3-5 years unopened; replace every 2 years or 40,000 km in service

When to Use / Replace?

Use JPN-DOT4 for daily commuting with occasional towing, mountain driving, or performance needs where brakes heat up fast. Switch to it if your vehicle manual calls for DOT 4, or upgrade from DOT 3 for better heat handling. Replace every 24 months or 30,000-50,000 km to avoid moisture buildup that lowers boiling point and causes spongy brakes. Check fluid color: dark or cloudy means flush now.
