Liqui Moly DOT 4: Reliable Stopping Power for Every Subie

When it comes to your brakes, there is zero room for compromise. Liqui Moly Brake Fluid DOT 4 is a premium synthetic fluid engineered to provide absolute reliability under pressure. Built on a sophisticated base of glycol ethers and alkyl polyglycols, it features extremely high wet and dry boiling points, ensuring your pedal stays firm and responsive even when the heat starts to climb during spirited driving.

This fluid doesn't just transfer pressure; it protects. It contains specialized inhibitors that prevent corrosion on metallic brake components and reduce oxidation at high temperatures. Plus, with special moisture scavengers, it actively guards against the formation of dangerous vapor bubbles—the leading cause of a "spongy" brake pedal.

Why Roo Racing Trusts Liqui Moly DOT 4:

• Highest Thermal Stability: Engineered to handle the high temperatures generated by performance disc and drum systems.

• Outstanding Protection Against Vapor Lock: Moisture scavengers keep your braking system safe and predictable over long service intervals.

• Excellent Low-Temperature Behavior: Provides consistent pedal feel and response even in the dead of winter.

• Lubricating Action: Specifically formulated to lubricate the moving components within your hydraulic brake circuit, extending the life of seals and pistons.

• ABS Compatible: Perfectly suited for use in modern Subaru ABS systems and clutch hydraulics.

• Elastomer Compatibility: Gentle on your rubber brake lines and internal seals to prevent leaks and swelling.

Roo Racing Maintenance Tip

Brake fluid is "hygroscopic," meaning it absorbs moisture from the air over time, which lowers its boiling point. For a car that sees enthusiastic use, we recommend a full flush every 12 to 24 months to keep that pedal feel crisp. Just a heads up: Brake fluid is a great paint stripper! If you spill any on your guard, wash it off with plenty of water immediately.
