High-performance synthetic engine oils engineered for smoother riding,
maximum engine protection, improved throttle response, and longer engine life.
Liqui Moly Brake Fluid DOT 4 (250ml) is a premium, synthetic brake fluid formulated in Germany to meet and exceed the stringent demands of modern automotive and motorcycle braking systems. Engineered for both disc and drum brakes, as well as vehicle hydraulic clutch systems, this fluid ensures instantaneous, reliable stopping power under both everyday driving conditions and extreme thermal stress.
The 250ml compact bottle is the ideal size for complete fluid top-offs, motorcycle brake system flushes, or small-capacity automotive hydraulic maintenance.
Key Features
-
High Boiling Points: Formulated with an exceptionally high dry boiling point ($\ge \text{260}^\circ\text{C}$) and wet boiling point ($\ge \text{155}^\circ\text{C}$). This prevents “brake fade” and ensures consistent pedal feel even during heavy, prolonged braking down steep grades or on the track.
-
Excellent Vapor Lock Protection: Contains advanced additives that combat moisture absorption (hygroscopy), preventing the formation of steam bubbles within the brake lines that lead to a dangerous, “spongy” brake pedal or lever.
-
Superb Viscosity-Temperature Behavior: Maintains outstanding fluid mobility and hydraulic pressure transmission across an extreme temperature range, ensuring rapid brake response in freezing winter conditions or scorching summer heat.
-
Elastomer & Seal Compatibility: Completely neutral toward the rubber cups, hoses, and synthetic seals used within master cylinders and brake calipers, preventing fluid leaks and seal degradation.
-
Advanced Corrosion Inhibitors: Contains specialized chemical inhibitors that actively protect internal metal components (including steel, cast iron, aluminum, and brass) against oxidation and rust.
-
Fully Mixable: Compatible and safely miscible with all high-quality synthetic brake fluids meeting the same DOT 3 or DOT 4 specifications (though a complete flush is recommended for maximum performance).

Application & Maintenance Tips
-
System Flush: For safety and peak performance, brake fluid should be completely replaced every 1 to 2 years (or as recommended by your vehicle manufacturer), as it naturally absorbs moisture over time.
-
Keep Contaminants Out: Always store brake fluid in its original, tightly sealed container. Even brief exposure to air allows the fluid to absorb ambient moisture, drastically lowering its boiling point.
-
Handle with Care: Avoid spilling brake fluid on vehicle paintwork, as it can chemically strip and damage automotive paint finishes. If a spill occurs, rinse immediately with plenty of water.
-
Safety Warning: DO NOT mix glycol-ether-based DOT 4 fluid with silicone-based (DOT 5) or mineral-oil-based (LHM) hydraulic fluids.
Why Choose Liqui Moly Brake Fluid DOT 4?
-
German Safety Engineering: When it comes to brakes, there is no room for compromise. Liqui Moly manufactures this fluid to the highest European standards, offering dependable reassurance when you step on the brakes.
-
Perfect for Motorcycles: Most motorcycles require less than 200ml for a complete front and rear brake bleed. This 250ml container allows you to perform a fresh fluid flush without having a large, leftover amount sit on a shelf absorbing moisture and going to waste.
