Remove

the
pump
from

and
test
as
follows

Connect
the

pump
to
a

fully
charged
battery
If
the

pump

now

operates
and

discharges
fuel

correctly
the
fault
does
not

lie
in
the

pump
but

may
be
attributed
to

any
of
the

following

causes

Battery
voltage
drop

poor
battery
earth
loose

wiring

loose
connections
blocked
hoses
or
a

faulty
carburettor

If
the

pump
does
not

operate
and

discharge
fuel
when

connected
to
the

battery
then
the

pump
itself
is

faulty
and

must
be
checked
as
follows

First
make
sure
that
current
is

flowing
This
will
be
indica

ted

by
sparking
at

the
tenninals
If
current
flows
the
trouble
is

caused

by
a

sticking

pump
plunger
or

piston
The

pump
must

be
dismantled
in

this
case
and
the

parts
thoroughly
cleaned
in

petrol

If

the
current
does
not
flow
a
coil
or
lead
wire
is
broken

and
the

pump
must

be
renewed
A

reduced

is
caused

by

DESCRIPTION

The
vehicle
is
fitted
with
disc
brakes
for
the
front
wheels

and
leading
trailing
shoe

type
drum
brakes

for
the
rear
wheels

A
conventional

single
master

cylinder
is
fitted
to

the

Standard
and
DeLuxe
models
See

Fig
D
I
for
details
The

DeLuxe
models
are
however
additio

ally
equipped
with
a

Master
Vae
servo

unit
which

provides
a

much
higher
braking

performance
with
minimum
force

required
on
the
brake

pedal

A
tandem
master

cylinder
and
Master
Vac
servo
unit
are

fitted
as
standard

equipment
to
the
Datsun
CL30UA
and
CL3

OUT
models
Fig
D
2

gives
an

exploded
view
of
this

type
of

master

cylinder

The
handbrake
is
of
the
mechanical
type
with
the
handle

linked
to
the
rear
shoe

operating

lever
through
a
system
of

rods
and
wires
See

Fig

As
on

previous
models
a

brake

pressure
differential
warn

ing
light
switch
is

incorporated
with
dual
brake
circuits
The

front
and
rear
brake

systems
are
connected
to
the
switch
which

provides
a

warning
via
a

warning
light
on
the
instnllnent
panel

when
a

pressure

of
13

occurs
between
the

BRAKE
Friction

pads

The
disc

but
the
friction

pads

should
be
checked
for

6
000
un
4
000
miles

and
then

every
5
000
km
3
000

The

pads
must
be

replaced
if
the
friction

lining
on

any
pad
has
worn
to
less
than

1
0
mm
0
04

The
thickness
of
the

pads
can

easily
be
checked
after
remov

ing
the
