Brake Master Cylinder-
I! there is
evidence
of leakage in
the
brake hydraulic system, the leak should be corrected and fluid
added if needed;
otherwise,
it should be checked at
the
time of
brake adjustment. (When adding brake
fluid
GM or Delco Super
9
Brake Fluid is
recommended.)
Front Wheel
Bearings-Should be lubricated only when it
is
necessary to remove the wheels and drums for
other
work
such
as
brake relining.
The
amount
of
high quality lubricant used at
the
time
of manufacture is entirely adequate for this period. If the wheel
bearings are found to
be
discolored
(turning
blue
or
straw colored)
it does not mean that they have been heated due to lack
of
lubricant.
This
discoloration is merely a
chemical
reaction of substances in the
lubricant
and does not affect
the
serviceability of the bearing in
any
manner.
When lubricating, the bearing should be cleaned and
packed with high melting point wheel bearing grease. The im-
portance
of
properly adjusting wheel bearings after lubrication
should
not
be
overlooked.
ReClT
Springs-Lubricate by repocking
spring covers with
chassis
lubricant when squeaks
develop.
Rubber bushings are used
in
the
rear spring shackles AND
ARE NOT TO
BE
LUBRICATED.
Steering Column GeClT Shift
Controls-
The
steering column
gear
shift
control linkage is
lUbricated
at assembly and requires
further
lubrication with Lubriplate
only when
the ports become dry
and
sticky
.
Hydra-Malic Linkage-
Lubricate
with
light
engine oil every 2,000
miles.
Shock
Absorbers-Front and rear shock absorbers
should be
checked
for leaks and their
operation
tested by
jouncing
the
car
at
each
lubrication. I! inoperative, or leaks are found, the unit must be
replaced
.
Speedometer Drive
Cable-To
be lubricated when dry
-
usually
noticeable by a wavering
of
the speedometer
needle
. A
very dry
cable, of course,
will be noisy.
Use
a
suitable
speedometer
cabl~
grease
which will not become
hard
and
stiff
when
cold.
Door and Rear Deck
Locks-Whenever
it
becomes difficult
to
insert the key
in
the
lock,
a
small
amount
of powdered graphite can
be blown into the lock cylinder.
