SERVICING
From the point
of
vi ew of
t
raffic safety, th
e
condition
of the
brakes
is
an extremely important factor.
It
is
essential,
therefore,
that any work carried
out on
the system should be done
by qualified mechanics
with the greatest
care, likewise
that
a
regular
check
is made
accord
ing
to the instructions
given
below.
CHECKING THE BRAKE FLUID LEVEL
When filling the tank with
fue
l,
check
to make
sure
that the fluel level
in
the master
cyl inder container
is
nO'j- below
the "Min"
marl<. This can be done without
removing the
cap.
Every 10000 km
(6000
miles) top-
up,
if necessary, to
the
"Max" container marl<.
A first-class brake
fluid which
meets the
require-
ments according to SAE 70 R 3 should be
used for
topping-up. Before removal, clean the cap of
the
con-
tainer and observe maximum cleanliness when filling
with fluid. Avoid spi
lling
the
brake fluid onto the
paintwork as this can damage
it.
Check to make sure
that the
vent-hole in
the cap
is
not blocked.
CHECKI
NiG THE
B
'
R
AKE PADS
Every 10000 km
(6000
miles) check the wear
on
the
linings.
The
brake pade should
be
replaced when the
linings are worn down
to
a thickness of about 3 mm
5:6
(1/8").
Und
e
r no circumstan ces mu st the
linings be
worn down below 1.5 mm (1/6"). For repla cement of
the pads, see pages 5 : 10 and 5
:
11.
FUNCTION CHECK
In
addition
to the regular
check
on the brakes
carried
oul' by the driver
as
result of the driving
done, the brakes
sho
uld
be
checked every
10000 km
(6000
miles) by
a
workshop mechanic.
The
footbrake
should also
be
che
cked
then to make sure that it func-
tions satisfactorilYi
if
necessary, check
with the help
of proper testing equipment (see "Fault
Tracing").
A
check should also
be made
that there
is no leakage
and
that the brake lines
are
not
exposed
to
such
damage
that leakage
can be expected. The
hand-
brake
should provide full braking power at the 3rd-
4th ratchet segment. If
it
does
not
do so, adjust the
handbrake
according to the
instructions
given on
page 5 : 34.
OVERH
AUL
Every third
year
or 60000 km (36000 miles) the brake
system seals and air filter for
the
servo brake
cy
lin
-
der should be replaced.
