Purpose and Specifications

SWAG 99 90 0001 is premium DOT 4 brake fluid in a convenient 0.25-liter bottle, weighing just 0.3 kg. It delivers reliable braking performance by resisting boil-off during hard stops, maintaining pedal firmness even after absorbing moisture over time. This fluid protects against corrosion in brake lines, calipers, and master cylinders, ensuring smooth operation in everyday driving and spirited performance.

Key specs include a dry boiling point of 260°C for fade-free braking in hot conditions like track days or mountain descents, and a wet boiling point of 160°C after moisture exposure, far exceeding basic requirements for long-term safety.

When to Use / Replace?

Use SWAG DOT 4 fluid in vehicles requiring DOT 4 specification, including popular models from Audi, BMW, Volkswagen, Mercedes-Benz, and many others like Fiat, Ford, Honda, and Porsche. It's a direct match for OEM part numbers such as VW B 000 750 M1 and BMW 81 22 9 407 512.

• Replace every 2 years or 40,000 km: Brake fluid absorbs water, lowering its boiling point and risking brake fade or corrosion.
• Flush if brakes feel spongy, during caliper service, or in high-heat driving (above 100°C wheel temps).
• Shelf life: 3-5 years unopened in cool, dry storage; always check for cloudiness before use.
