Purpose and Specifications

WOLF DOT 3&4 Brake Fluid is a budget-friendly 1-liter solution for hydraulic brake, clutch, and steering systems in passenger cars. This versatile fluid meets DOT 3 and DOT 4 standards, delivering high chemical stability to prevent residue buildup and superior oxidation resistance for long-lasting protection. It operates reliably from -40°C to 260°C, ensuring smooth performance in cold starts and extreme heat without boiling or fading brakes.

Key practical benefits include excellent corrosion protection for your entire brake system, compatibility with all rubber seals and components, and a high dry boiling point of 263°C (over 500°F) to maintain firm pedal feel during hard stops. The wet boiling point stays strong at 165°C even after absorbing moisture, outperforming standard DOT 3 fluids for safer, longer service life.

When to Use / Replace?

Use WOLF DOT 3&4 in any vehicle specifying DOT 3 or DOT 4 fluid, including ABS, disc, and drum brakes. It's ideal for daily drivers and spirited road use where heat builds up quickly.

• Replace every 2 years or 40,000 km (whichever comes first) to avoid moisture buildup that lowers boiling point and causes spongy brakes.
• Flush if brakes feel soft, pedal sinks, or during routine maintenance.
• Shelf life: 3-5 years unopened in a cool, dry place.

FAQ

Can I mix WOLF DOT 3&4 with existing brake fluid?
Yes, it's fully compatible with other DOT 3 or DOT 4 glycol-based fluids for easy top-offs or flushes.

Is it safe for my motorcycle or classic car?
Perfect for most bikes and cars calling for DOT 3/4; avoid DOT 5 silicone types. Check your owner's manual.

Why does brake fluid need changing?
It absorbs water over time (up to 2% per year), dropping its boiling point and risking brake failure in hot conditions.
