Purpose and Specifications

LIQUI MOLY 3085 Brake Fluid DOT 4 is a premium synthetic brake fluid designed for reliable braking in all disk and drum systems, plus clutches and ABS/ESP setups. It delivers a high boiling point to stay effective under extreme heat from hard braking, preventing steam bubbles that could fade your brakes. Special additives fight corrosion on metal parts, lubricate moving components to cut wear, and handle moisture absorption for safe performance over time. Excellent cold-weather flow ensures quick response even in freezing temps down to -40°C, while staying thick enough at high temps over 200°C for track or towing demands. Comes in a 500ml box for easy pro-level changes.

When to Use / Replace?

Use this DOT 4 fluid in any vehicle calling for DOT 3, DOT 4, or compatible specs per your owner's manual - perfect for daily drivers, performance cars, or heavy-duty trucks. Replace every 2 years or 40,000 km to avoid moisture buildup that drops boiling point and risks brake failure. Shelf life is 5 years unopened; check fluid color - dark or cloudy means swap it now for safety. Ideal during brake jobs, annual service, or if brakes feel spongy.

FAQ

Q: Can I mix this with my old DOT 4 fluid?
A: Yes, it's fully miscible with quality synthetic DOT fluids, but for peak performance, flush the system completely during changes.

Q: Is it safe for my ABS system?
A: Absolutely - optimized for modern ABS, ESC, and hydraulic clutches with superior viscosity for fast, precise response.

Q: How do I know when boiling point drops too low?
A: Test annually; if wet boiling point falls below 155°C from moisture, replace to keep brakes firm and safe.
