Purpose and Specifications

Keep your brakes responsive and safe with MAPCO 9040/4 DOT 4 Brake Fluid, a reliable mid-range choice in a convenient 20-liter canister. This glycol-based fluid excels in high-heat conditions, staying fluid up to 260°C dry and 160°C wet, preventing brake fade during hard stops or downhill drives. It fights moisture absorption to cut corrosion on calipers and master cylinders, extending component life while working seamlessly with ABS and modern braking systems.

• Perfect for workshops handling fleet maintenance or bulk flushes
• Compatible with DOT 3 systems for easy top-ups
• Meets ISO 4925 Class 6 standards for consistent performance

When to Use / Replace?

Use MAPCO 9040/4 for everyday cars, trucks, and European vehicles facing stop-go traffic or towing. Replace every 2 years or 40,000 km to avoid moisture buildup that lowers boiling point and risks vapor lock. Ideal operating range: -40°C to 200°C+ for all-season reliability. Shelf life is 3-5 years unopened; store cool and dry.
