ISO 4925 CLASS 4

ISO 4925 Class 4 is an international standard that defines the requirements for brake fluids, including their thermal stability, viscosity, and hydraulic properties. Within the manufacturers' (OEM) specifications, this class meets the requirements for DOT 4 type fluids and is suitable for most passenger cars that require a high boiling point and resistance to heating during intensive braking. When selecting a fluid, you should ensure that your vehicle’s technical documentation specifically lists ISO 4925 Class 4; otherwise, warranty service may be compromised. This specification guarantees compatibility with brake systems designed for this classification and ensures safe operation of the braking equipment.
