Purpose and Specifications

MA PROFESSIONAL DOT4 500ml brake fluid delivers reliable stopping power for everyday cars, trucks, and performance vehicles. This mid-range synthetic glycol-based formula resists boiling during hard braking, staying effective from -40°C in freezing winters to over 230°C under heavy use. It protects against corrosion, lubricates brake components for smooth action, and works with most hydraulic systems.

• 500ml bottle fills small systems or tops off larger ones
• High wet boiling point above 155°C prevents vapor lock even when moisture builds up
• Excellent cold flow keeps brakes responsive in sub-zero temps
• Compatible with DOT 3 and 4 systems for easy upgrades

When to Use / Replace?

Use MA PROFESSIONAL DOT4 in vehicles with ABS, clutches, or high-heat braking like sports cars or heavy haulers. Replace every 2 years or 40,000 km to avoid moisture absorption that lowers performance. Opened bottles last 1 year if sealed tight in a dry spot; unopened shelf life reaches 5 years.
