Brake system, bleeding

Brake system, bleeding (vehicles with
and without ABS, ABS/EDL)

Changing brake fluid
Repair Manual, Maintenance
Note:
Bleeding the brake system on vehicles with
ABS, ABS/EDL is performed as for vehicles
with conventional braking systems.
Only use new brake fluid conforming to US
standard FMVSS 116 DOT 4.
Genuine VW/Audi brake fluid conforms to this
specification.
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 always be stored in air tight containers.
Rinse off spillages using plenty of water. Repair Manual, Brake System On Board Diagnostic (OBD), Repair Group 01 Page 1 of 3Brake system, bleeding12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.47.6
