t  Genuine VW/Audi brake fluid conforms to this specification.
t  Brake fluid is poisonous. Also due to its corrosive effect brake fluid must not come into contact with paintwork.
t  Brake fluid is hygroscopic, which means it absorbs moisture from the ambient air and should therefore always be stored in air tight containers.
t  Wash away spilt brake fluid using plenty of water.
A pre-pressure of 2 bar is required for bleeding the hydraulic unit.
