GROUP 2-Brakes
Be sure that the tabs on the shoe
flanges seat fully against the caliper
bridges (Fig. 18).
2. Position the spring clips on the
calipers and install the retaining bolts
and washers (Fig. 17).
3. Pump the brake pedal several
times until a firm pedal is obtained
and the shoe and lining assemblies
are properly seated.
4. Install the wheel and tire on the
hub and rotor assembly.
5. Check and refill the master cyl-
inder reservoir with specified brake
fluid as required.
It should not be
necessary to bleed the system after
a shoe and lining replacement.
6. Road test the vehicle.
DISC BRAKE CALIPER
ASSEMBLY
REMOVAL
Refer to Figs. 17 and 25.
1. Remove the front wheel cover.
Remove the wheel and tire from the
hub and rotor assembly.
Be careful
to avoid damage or interference with
the caliper bleeder screw fitting or
transfer tube.
2. Disconnect the steel brake line
transfer tube from the caliper. Dis-
connect the front brake tube assem-
bly from the brake hose.
3. Remove the spring lock clip. Re-
move the hose from the caliper. Re-
move the two bolts attaching the
caliper assembly 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 and place it on the bench.
INSTALLATION
Refer to Figs. 17 and 25.
I. Position the caliper assembly on
the rotor, and mate the mounting bolt
holes on 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 assembly and
the rotor. The shoe and lining assem-
blies should be seated properly
' on
the bridges.
2. lnstall the caliper to spindle at-
taching bolts and torque them to
specification. lnstall the safety
wire on the bolts (if so equipped).
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.
6).
3. Position a new gasket between
the hose fitting and caliper. Connect
the hose to the caliper and torque
it to specification. Refer to Figs.
20 and 21. Position the caliper as-
sembly to the spindle. lnstall the re-
taining bolts and torque them to
specification. Install the safety wire
(if so equipped) on the bolts. lnstall
the female fitting end of the hose in
the side-rail bracket.
The stripe on
the hose must show no evidence of
twist.
4. Install the spring lock clip. Con-
nect the tube assembly to the hose,
and torque the tube connector to
specification. Refer to Figs. 20 and
21. Bleed the brake system and
centralize the differential valve as
outlined in Part 2-1. Check the mas-
ter cylinder fluid level and add the
specified fluid, as required.
Pump
the brake pedal several times to
actuate the piston seals and to posi-
tion the shoe and lining assemblies.
5. Install the wheel and tire and
the wheel cover.
6. Road test the vehicle.
FRONT WHEEL HUB AND
ROTOR ASSEMBLY-DISC
BRAKES
REMOVAL
I. Remove the wheel and tire from
the hub and rotor assembly (Fig. 17).
Be careful to avoid damage or inter-
ference 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 vehicle. 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,
scratching or contamination 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
bezring cone and roller assembly.
4. Remove the hub and rotor as-
sembly from the spindle.
INSTALLATION
1. If the rotor is being replaced,
FIG. 18- Removing Disc Brake
Shoe and Lining
Assem bly-Typical
remove the protective coating from
the new rotor with carburetor
de-
greaser. Pack a new set of bearings
with specified grease, and install the
inner bearing cone and roller assem-
bly
in the inner cup. Pack grease
lightly between the lips of a new
grease retainer and install the re-
tainer (Fig. 17).
If the original rotor is being in-
stalled, make sure that the grease in
the hub is clean and adequate, that
the inner bearing and grease retainer
are lubricated and in good condition,
and that the rotor braking surfaces
are clean.
2. lnstall the hub and rotor as-
sembly on the spindle.
3. Lubricate and install the outer
wheel bearing, washer and adjusting
nut.
4. Adjust the wheel bearings to
specification, and then install the
nut lock, cotter pin, and grease cap.
The wheel bearing adjustment is es-
.pecially
important with disc brakes.
5. Mount the caliper assembly on
the mounting bracket and torque the
two attaching' bolts to specification.
If necessary,' push the caliper pistons
into the cylinder bores to obtain
clearance between the shoe and lin-
ing assemblies and the rotor. Be sure
that the shoe and
lining assemblies
are seated on the bridges. Check the
flexible hose for correct routing.
6. lnstall the wheel, tire and cover
on the hub and-rotor assembly.
