Purpose and Specifications

SWAG 99 90 0004 is premium DOT 4 brake fluid designed to deliver reliable braking performance in modern vehicles, including Mercedes-Benz models meeting MB 331.0 standards. This synthetic fluid resists boiling even under intense heat from hard braking, staying effective up to 260°C dry and 180°C wet after absorbing moisture over time, preventing brake fade and ensuring crisp, responsive stops.

Packaged in a convenient 0.25-liter bottle weighing just 0.3 kg, it's perfect for topping off or full flushes. It flows smoothly in cold weather for quick ABS and traction control response, while protecting against corrosion in your brake system for longer component life.

When to Use / Replace?

Use SWAG DOT 4 brake fluid in any vehicle specifying DOT 4, especially high-performance cars or those with advanced braking systems. It's fully compatible and exceeds ISO 4925 standards for superior safety.

• Replace every 2 years or 40,000 km: Brake fluid absorbs water from air, dropping its boiling point and risking vapor lock during stops.
• Flush immediately if brakes feel spongy, pedal sinks, or during routine service to maintain peak stopping power.
• Shelf life: 3-5 years unopened in a cool, dry place; always check for discoloration before use.

FAQ

Can I mix this with other brake fluids? Yes, it's backward compatible with DOT 3 and safe with DOT 4 systems, but for best results, flush completely when switching brands.

Is it suitable for racing or track use? Absolutely - its high boiling point handles extreme heat from repeated hard braking, outperforming basic DOT 3 fluids.

How much fluid for a full brake flush? Most cars need 0.5-1 liter; this 0.25L bottle is ideal for partial refills or smaller systems.
