DESCRIPTION

The
Datsun
1200

series
new
models

adopt
a

hydraulic

brake

Dis
brake
or
two

leading
shoe

type
drum
brake
is

used
for
the
front

wheels
and

leading
trailing
shoe

type

drum
brake
is
used
for
the

rear
wheels

With

adoption
of
the

disc
brake

safety
at

high
speed

range
driving
is
further

improved

For
the

master

cylinder
either

single
type
or
tandem

type
is
used

There
are
two

types
of
tandem

type
master

cylinder
one
is
for
disc

brake
and
the
other
for
drum

brake
Under
the

standard

specifications
h0wever
the

tandem

type
master

cylinder
is

used
for
disc
brake
and

single
type
is
used
for
drum

brake

The
tandem

master

cylinder
provides
a
dual

brake

system
improving
safety

The
hand
brake
is
of

a
mechanical

type
which
brakes

the
rear

wheels

through
the
control
lever

and
steel
wire

The

control
lever
is
located
between
the
driver
and

assistant
seats
and
can
be

operated
easily

BRAKE
PEDAL

The

steering
colunm
bracket

supports
the
brake

pedaL

The
brake

pedal
is
instaUed
on
the

steering

bracket
with
a
fulcrum

pin
The
brake

pedal
arm
and

brake

are

joined
with
a
