Abstract (en)

A lubricant hydraulic fluid, in particular brake fluid, with improved lubricant properties and anti-wear protection, is composed of a commercially available brake fluid with usual additives and of a combination of a least one metallic dialkyldithiocarbonate and at least one metallic dialkyldithiophosphate as lubricant additive. Also disclosed are a process for producing the same and its uses as working fluid for central hydraulic systems, in particular as brake fluid, for servo-steering, central locking, spring hydraulic systems and the levelling and ventilating hydraulic systems of vehicles, in particular motor vehicles.
