Front wheel camber, adjusting Note: - Install special tool as shown in illustration and
slightly pre-tension.
- Loosen suspension strut/wheel bearing housing
connection.
- Adjust camber by turning the spindle to specified
setting.
- Tighten suspension strut/wheel bearing housing
connection.
- Check camber and if necessary, repeat
adjustment. Slight cant of tool is permitted. Do not move steering with tool in place! Before adjusting camber, it is essential to
examine all suspension components for damage
(visual inspection) and to replace any damaged
parts. Because bolts with a shank diameter of 11 mm
diameter have been installed as standard it is no
longer necessary to replace bolts to correct
camber. Page 6 of 7Vehicle alignment12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.44.1

6 - Brake servo On gas engines the
vacuum required is
taken from the intake
manifold. On Diesel engines an
exhauster is installed
to create the required
vacuum. Functional check - With engine
switched off,
depress brake pedal
firmly several times
(to exhaust the
vacuum in the unit).
- Now depress brake
pedal with average
foot pressure, hold
and start engine. If
the servo unit is working properly, the pedal will be felt to
give slightly under
foot (servo
assistance becomes
effective). If faulty replace
complete. Check valve (item 14 )
is in vacuum hose Functional check - It must be possible
to blow through in
direction of arrow.
- Blowing against the arrow the valve must seat. Page 2 of 4Assembly overview: brake master cylinder/brake servo12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.47.1

Checking toothed rod for scoring If corroded areas or deep scratches are not
noticeable on the toothed rod, the toothed rod must
be replaced
An evaluation of whether the toothed rod was
damaged by force, e.g. by an accident, is not possible
with this visual inspection
If slight scoring (arrows) can be seen/felt on the
toothed rod that are only deep enough that they can
be ground off with sand paper (grain 350-600) the
toothed rod can still be used After sanding, lubricate toothed rod lightly
If the old toothed rod is used again, check the sealing
ring for scoring (visual inspection). If there is scoring
that can be seen or felt, the sealing ring and the O-
ring under it must be replaced. - Sand toothed rod with sandpaper in radial direction (this is only possible with slight scoring)
- Check chamfer on the front sides of the toothed
rod for damage, if necessary remove with a fine
grinding stone and/or sandpaper
