Some
bolts
are
designed
to
stretch
during
assembly
and
are

permanently
altered
rendering
them
unreliable
once
removed
.

These
are
known
as
torque-to-yield
fasteners
.
Always
replace

.
Failure

Tightening
Fasteners

When
tighteningthe
bolts
ornuts
that
attach
acomponent,
it

is
always
good
practice
to
tighten
the
bolts
gradually
and
evenly

to
avoid
misalignment
or
over
stressing
anyone
portion
of
the

component
.
For
components
sealed
with
gaskets,
this
method

helps
to
ensure
that
thegasket
will
seal
properly
and
complete-

ly
.

Where
there
are
severa¡
fasteners,
tighten
them
in
a
se-

quence
alternating
between
opposite
sides
of
the
component
.

Fig
.

shows
such
a
sequence
for
tightening
six
bolts
attaching

a
typical
component
.
Repeat
the
sequence
until
al¡
the
bolts
are
evenly
tightened
to
theproper
specification

Brake
Fluid

Brake
fluid
absorbs
moisture
easily,
and
moisture
in
the
fluid
affects
brake
performance
and
reliability
.
This
is
why
brake
fluid
should
be
flushed
from
the
system
every
two
years
.
When
re-
placing
or
adding
brake
fluid,
use
only
new
(luid
from
previously
unopened
containers
.
Do
not
use
brake
fluid
that
has
been
bled
from
the
system,
even
ifit
is

.
Use
only
