As more vehicles operate under harsh conditions\u2014high temperatures, hilly terrains, urban traffic\u2014the choice between DOT 4 vs DOT 5.1 becomes crucial.For markets in Africa, Southeast Asia, South America, and Central Asia, where ambient conditions and vehicle load stress braking systems, selecting the right fluid ensures longer system life, safety, and optimal performance. Key Difference: DOT4 vs DOT 5.1 Explained Both DOT 4 brake fluid and DOT 5.1 brake fluid are glycol-based and compatible with ABS, ESP, and modern hydraulic brake systems. However, the difference lies in boiling point and viscosity, which are critical for braking safety. Specification DOT 4 DOT 5.1 Dry Boiling Point \u2265 230\u00b0C \u2265 260\u00b0C Wet Boiling Point \u2265 155\u00b0C \u2265 180\u00b0C Viscosity @ -40\u00b0C Higher (~1800) Lower (~900) Fluid Base Glycol Glycol Why Oil Change Interval Science Matters 5.1 brake fluid offers faster response in extreme cold and resists fade under prolonged braking.Explore TERZO DOT 4 Brake Fluid \u2014 trusted worldwide.
