ISO 4925 CLASS 6

ISO 4925 CLASS 6 is an international standard that defines the requirements for brake fluids. Class 6 meets the DOT 4 specifications: dry boiling point not less than 230 °C and wet – not less than 155 °C, which ensures stable brake performance under intensive heating. If your vehicle or OEM‑requirements specify a class 6 brake fluid, choose products certified to this standard, such as the premium synthetic fluid X‑BRAKE DOT4. This fluid is suitable for passenger cars and off‑road vehicles that require high thermal resistance and corrosion protection.
