OPERATING
INSTRUCTIONS
BRAKE
SYSTEM
The
following points are of particular
importance to the safe operation of the
brakes.
• New brake linings must also be run in
and
do not have the optimum friction
properties during the
first
200 km. The
slightly reduced braking effect can be
compensated
for by slightly more pres-
sure
on the brake
pedal.
This also applies
when new linings have been fitted.
• On hills change down in good time to
make
use of the braking effect of engine.
This
relieves strain on the brake system.
When
brakes are applied do not keep
them on continuously, apply and release
alternately.
• In certain operating conditions, for
example
after driving through water,
after heavy rain or after washing the
•vehicle
the braking effect may be re-
tarded by wet, or in winter iced-up brake
discs
and linings - the brakes must be
dried
first
by applying the footbrake.
The
full
braking force may also be re-
tarded when vehicle has been driven for
some
time on heavily salted roads with-
out using the brakes because the layer
of salt on
discs
and pads has to be re-
moved
first.
Further details - particularly for vehicles
with
four wheel drive - are given on page
66.
• Brake lining wear depends to a large
extent on the operating conditions and
style of driving. On vehicles which are
used
mainly in town
traffic
and stop/start
conditions or are driven hard it may be
necessary
to have the thickness of the
brake linings checked in a V.A.G work-
shop
in between the intervals given in
the service schedule.
• If the brake pedal travel increases
suddenly,
it may be
that
one of the two
brake circuits has failed. You can still
drive on to the next
V.A.G
workshop but
be
prepared to use more pressure on
the pedal and allow for longer braking
distances
on the way.
The
failure of a brake circuit is shown by
the lighting up of the brake warning
lamp*
(see also page 36).
The
brake fluid level must be checked
regularly - see next page.
Brake
servo
The
servo is operated by vacuum which
is
only available when engine is running.
Caution
For
this
reason
the
vehicle
should not
be
allowed
to
roll
with
engine
not run-
ning.
When
the brake servo is not working be-
cause,
for example, the vehicle is being
towed or because a defect has occured
on the brake servo, the brake pedal must
be
pressed harder.
