CALIPER
ASSEMBLY
REMOVAL
1.
Remove the
wheel
and
tire from
the
hub
and
rotor
assembly. Be
careful
to
avoid
damage
or in
terference
with
the
caliper splash
shield,
bleeder
screw
fitting
or transfer
tube.
2.
Disconnect
the
front brake flex
ible
hose
from
the
brake tube
at
the
bracket on
the
frame (Fig.
16).
3.
Remove the
two
bolts
that
at
tach the
caliper
to the spindle.
Take
care
to avoid
loosening
the
bridge
bolts
that hold
the
two halves
of the
caliper
together.
4.
Lift the
caliper
assembly
off the
rotor.
INSTALLATION
1. Position
the caliper
assembly
on
the
rotor,
and mate the
mounting
bolt
holes in the caliper
with those in
the
spindle.
It
may
be
necessary
to
push
the caliper
pistons into
the
cylinder
bores to obtain clearance
between
the
shoe and
lining
assemblies and the
rotor.
The shoe
and
lining
assemblies
should
be
seated
properly
on the
bridges.
2. Install the caliper
to
spindle
retaining
bolts and torque to specifica
tion. Note the
difference in bolt
lengths. Check to insure
that
the rotor
runs
squarely
and
centrally
between
the two
halves
of the caliper. There
should
be
approximately
0.090-0.120
inch clearance between
the caliper and
the
rotor outside diameter
(Fig. 2).
3.
Connect the front wheel brake
flexible hose to the
brake tube at the
bracket on
the frame (Fig.
16).
The
hose should be
checked
for
correct
routing.
4.
Bleed the
brake
system
as
outlined
in
Section 2-1. Check
the
master
cylinder fluid
level,
and the
specified brake
fluid as
required.
5.
Pump
the
brake pedal
several
times to actuate the
piston seals
and
to position
the
shoe
and
lining
as
semblies.
6.
Install
the wheel and tire.
7. Roadtest the car.
FRONT
WHEEL HUB
AND
ROTOR
ASSEMBLY
REMOVAL
1. Remove the wheel and tire
from
the
hub
and
rotor
assembly
(Fig.
8).
Be
careful to
avoid
damage
or in
terference
with
the
caliper
splash
shield,
bleeder
screw
fitting
or
transfer
tube.
2.
Remove
the
caliper
assembly
from the
spindle
and
the
rotor.
If
the
caliper does
not
require
servicing,
it
is
not
necessary
to
disconnect
the
brake
hose
or
remove
the
caliper
from
the
car. Position
the
caliper
out
of
the
way,
and
support it
with a
wire to
avoid
damaging
the
caliper
or
stretching
the
hose. Insert
a
clean
cardboard
spacer
between the
linings
to
prevent the
pistons
from
coming
out
of the
cylinder bores
while
the
caliper is
removed.
Handle the rotor
and caliper
as
semblies in
such a
way
as to avoid
deformation of
the rotor and
nicking
or
scratching
of
the
brake linings.
3.
Remove
the
grease
cap
from the
hub. Remove the cotter
pin,
nut
lock,
adjusting
nut,
and flat washer from
the spindle. Remove the outer
bearing
cone and roller assembly.
4.
Remove
the hub
and rotor
as
sembly
from the spindle.
INSTALLATION
1.
If
the rotor
is
being replaced,
re
move
the
protective
coating
from
the
