Purpose and Specifications

Keep your brakes responsive and safe with MAPCO 9040/5 Brake Fluid, a reliable DOT 4 formula in a convenient 5-liter canister. This mid-range quality fluid from MAPCO handles extreme heat up to 270°C dry boiling point and stays effective at 170°C even when wet with moisture, preventing brake fade during hard stops or track days.

• Meets ISO 4925 Class 6 standards for superior corrosion protection and smooth pedal feel.
• Compatible with most vehicles needing DOT 3 or DOT 4 fluid, including European and American cars.
• Absorbs moisture over time but maintains performance far longer than basic fluids.

When to Use / Replace?

Use MAPCO 9040/5 for routine brake flushes or top-ups in daily drivers, performance cars, or fleet vehicles. Replace every 2 years or 40,000 km to avoid spongy brakes from moisture buildup. Ideal for operating temps from -40°C cold starts to 200°C+ high-heat braking. Unopened shelf life is 5 years in a cool, dry place.

FAQ
