The parking brake
is
a mechanical type which
is
designed
to
actuate
the
travelling
brakes
through
the
linkage.
Pulling
the
parking
brake lever (3)
results in the
same
state
as
the
obtained
when
the
brake pedals are pressed.
*
Fade
Fade
is
a phenomenon
of
braking force
loss
caused
by
the
heat
generated
in
repeated
braking.
Generally,
the
friction
coefficient
of
brake disc
tends
to
lower
and
the
braking force reduces
with
the
rise
of
the temperature
of
the
brake disc.
(Reference)
• Relationship
between
temperature
and
friction
coefficient
of
brake disc.
Independent mechanical
wet
disc brakes are
used
for
the
right
and
left
travelling
brakes. They are
operated
by
the
brake
pedals
through
the
mechanical linkages and provide stable braking and
require
little
adjustment.

Features
of
Wet
Disc Brakes
1. Reduced disc
wear
Although
wet
discs are
worn
by approx. several
tens
of
microns
depending
on
the
accuaracy
of
parts
during
the
initial
contact in
initial
period
of
50 hours
or
so,
almost
no
wear
occurs afterwards.
This means
that
very
little
brake adjustments are
required.
2. Stable braking
Since
the
brake discs are immersed in transmission
oil,
Fade*
is
rarely
caused even
after
repeated
braking and a stable braking force
is
obtained.
3. Pedal stroke does
not
change under influence
of
heat.
Unlike internal expanding
type
brakes,
the
drum-
to-shoe clearance
of
the
wet
disc brake does
not
increase
due
to
thermal
expansion
and
the
increased pedal stroke does
not
result. Thus,
the
wet
disc brake provides a constant pedal stroke.
