Bleeding brake system
Bleeding the brake system is described using brake filling and
bleeding equipment -VAS 5234- .
WARNING
Only use new brake fluid conforming to VW standard
(VW 501 14).
Note
♦
Do not under any circumstances allow brake fluid to come into
contact with fluids that contain mineral oils (e.g. oil, petrol,
cleaning agents). Mineral oils damage the seals and packings
in the brake system.
♦
Brake fluid is poisonous. Also due to its corrosive effect brake
fluid must not come into contact with paintwork.
♦
Brake fluid is hygroscopic, which means it absorbs moisture
from the ambient air and should therefore always be stored in
air tight containers.
♦
Rinse off spilled brake fluid using plenty of water.
♦
Do not reuse drained (used) brake fluid.
♦
Always observe the relevant environmental regulations for
disposal
A pre-pressure of 2 bar is required for bleeding the hydraulic unit.
