DESCRIPTION

The
vehicle
is
fitted
with
either
disc

brakes
or
two

leading

shoe

type
drum
brakes
for
the
front
wheels
and

leading
trailing

shoe

type
drum
brakes
for

the
rear

wheels

All
brakes
are

hydraulically
operated
from
the
brake

pedal

with
the
rear
brakes

additionally
operated

by
a
mechanical

handbrake
and

linkage
system
Either
a

single
or
a
tandem

master

cylinder
can
be
fitted
The
tandem
master

cylinder

provides
a
dual

braking
circuit
in
which
the
front
and
rear

brakes
are

separately
supplied
If
ODe
circuit
fails
the
other

circuit
will

still

operate
and
provide
a
reduced
but
efficient

braking
action

The
brake

pipes
are

double
wall
steel
tubes
and
are

galvanized
at
the
sections
beneath
the
vehicle
floor
to

prevent

corrosion

Assembly
of

procedure
noting
the

following

The

layout
of
the
metal
brake

pipes
and
flexible

is

shown
in

Fig

The
brake

pipes
can

be
removed

by
taking
off
the

at
both
ends
of
the

pipe
and

removing
the

clips
securing

the

can
be
removed

by
taking
off
the

Thoroughly
clean
the

pipe
or
hose
after

removing
from

the
vehicle
and
check
for

collapsing
cracking
or

rusting
of

the

pipe
and
for

signs
of

expansion
and

weakening
of
the
hose

Any
pipe
or
hose
which
is
not
in
a

satisfactory
condition
must

be
renewed
Remove

any
dust
from
the
brake

clip
and
replace

the

clip
if
the

vinyl

is
torn

Installation
is
a

Make

sure
that
the
brake

pipes
cannot
vibrate

against
any
part
of

the
vehicle
and
the
brake
hoses
are
not
twisted
and

rubbing

against

If
the

is

disconnected
from

the

it
will
be
