lengthening of the brake master cylinder eye bolt.

This
is
done
so the primary cup
will
clear the by­
pass port when the piston is in the off position,
otherwise the compensating action of the master

cylinder
for expansion and contraction of the fluid
in
the system, due to temperature changes,
will

be destroyed and cause the brakes to drag.

Note:
Some older 'Jeep' vehicles may
develop
side

movement
of the clutch and brake pedals resulting
from wear of the pedals, shafts, and bushings. One
way to
compensate
for this wear is to install a pedal

slack
adjuster kit,

Hand Brake

On
Model DJ-5 and DJ-6 vehicles the rear brake

shoes
are operated through cables and conduits to
form the hand or parking brake. A brake cable
equalizer and adjusting rod, Fig. P-6, is located directly back of the frame center cross member.

P-11.
Parking Brake Adjustment

•
Model DJ-5, DJ-6.

The
foot
brakes must be satisfactorily adjusted be­
fore attempting adjustment of the hand brake.

To
adjust the hand brake raise both rear
wheels

free of the floor.
Pull
up three
notches
on the hand

brake
lever and tighten the adjustment until the

rear
brakes drag slightly. Release the hand brake
lever and check the rear
wheels
for drag. The

wheels
must turn freely with the lever released.

P-12.
Transmission Brake Adjustment
The
transmission brake is located on the propeller
shaft at the rear of the transfer case, see Fig. P-4.
The
brake is operated by a cable connection from
the brake handle mounted on the instrument panel.

To
adjust the transmission brake, the following

sequence
should be followed:
Make
sure that the brake handle on the instrument
panel is fully released. Give due attention to the
cable and operating linkage to see that
they
do
not bind. If necessary free up the cable and
lubri­
cate it. Rotate the brake drum until one pair of the
three
sets
of
holes
are over the
shoe
adjusting screw

wheels
in the brake. Use the
edge
of the
holes
in
the brake drum as a fulcrum for suitable adjusting

tool
or a screwdriver, rotate each notched adjusting
screw by moving the handle of the
tool
away from
the center of the drive shaft until the
shoes
are
snug in the drum.
Back
off seven
notches
on the
adjusting screw
wheels
to secure proper running clearance
between
the
shoes
and the drum. Refer
to Fig. P-8.

a.
To reline the brake
shoes
and make a major ad­
justment, first remove the four universal joint at­ taching nuts and lower the propeller shaft. Remove
the retracting spring clevis pin and the spring clip.
Remove the hug lock nut, the nut and washer from
the transfer case output shaft. Both the universal
joint companion
flange
and the brake drum may be readily removed by using puller Tool No. W-172

which
is illustrated in Fig. P-7. Remove the two

brake
shoe
retracting springs and the
shoes.

b. Clean all parts with a suitable cleaning solution

and
examine them for damage or wear.

Brake
shoes
may be distorted by improper lining
installation and the lining should be ground true
after installation on the
shoes.
For this reason it
is recommended that new or replacement
shoe
and
lining assemblies be installed.
c. To reassemble, first turn both adjusting screw

wheels
away from the center to "all off" position.
Place a light film of grease on the brake actuating

cam
and install the

g.
Reconnect the propeller shaft.
Install
retracting
spring
clip,
clevis pin and the cotter pin, also, in­

stall
the retracting spring
link
and spring.
h. The
position
of the brake operating lever, Fig.
P-8, must be correctly set. The
position
of this
lever
is determined by the adjustment of the cam or
brake operating
link,
which
spreads
the two
shoes.
The
operating
link
is adjusted by
means
of the

special
ball
nut to set the operating lever
with

[2,38
mm.] clearance between the closest
point

of
the lever and the brake backing plate.

i.
The
position
of
this
lever should be checked when

making
a major adjustment or when
relining
the
brakes and
if
found
incorrect readjust it to give this
clearance before adjusting the brake cable
clevis.

P-14.
Self-Adjusting
Wheel
Brake
Units
Self-adjusting
brakes are standard equipment on

all
late production
'Jeep'
vehicles.
The
wheel brake units consist of a support plate,

two
brake
shoes,
brake
shoe
return springs, self-

adjusting
operating parts, and a wheel
cylinder.
The
automatic adjuster continuously maintains

correct
operating clearance between the brake
lin­
ings
and the drums by adjusting the brakes
in
small

increments in direct
proportion
to
lining
wear. This
continuous
adjustment prevents gradual increase

in
the brake pedal
travel
as the
linings
wear. The
adjuster, therefore,
adds
the safety feature of
main­
taining
adequate
pedal reserve
during
the service

life
of the
lining.

After
the
lining
wears enough to require adjust­ment, the adjusting cable or
link
will lift
the lever

into
engagement
with
the next
tooth
of the
star

wheel
when the brake is applied. When the brake
is
released, the
shoes
return to the anchor. The
self-adjuster
utilizes
the movement of the brake

shoes
in a brake application to
actuate
the adjuster
lever.

This
action
will
repeat
on
subsequent
brake applica­

tions,
if
necessary,
until
the
shoe
to
lining
clearance
is
reduced to a
point
where the
shoe
movement

is
not enough to
cause
the cable to
lift
the lever

to
the next
tooth.

The
adjusting lever, adjusting screw assembly,

linkage
rods and lever crank parts are
left
hand
or
right
hand parts, NOT interchangeable, and
MUST
be kept
separated.

The
automatic adjuster on the brake system con­

sists
of an adjusting screw assembly, adjusting

lever,
two adjusting
links,
and a lever crank, (Fig.
P-10).

Note:
It is not
necessary
to remove the rear axle
shaft hubs to
perform
minor
brake service.

When
replacement of
oil
seals
is also required, hubs must be removed.

On
vehicles equipped
with
self-adjusting brake
assemblies, self-adjustment of the
front
wheel brakes
takes
place
during
reverse wheel brake ap­

plication
and the rear wheel brake adjustment
takes

place
during
forward
vehicle brake application.

P-17. Inspection
Inspect the oil seals in the wheel hubs. If the con­
dition of any oil seal is doubtful, replace it. Install
the oil seal with an oil seal driver as shown in Fig.

P-9.

Brake
shoes
may be distorted by improper lining installation and linings should be ground true. For
this reason it is recommended that new or re­
placement
shoe
and lining assemblies be installed.
Using
brake drum micrometer C-3920 or equi­
valent, check all drums. Should a brake drum be rough and scored, it may be reconditioned by grinding or turning in a lathe. Do not remove more
than .030"
[0,762
mm.] thickness of metal .060" [1,52 mm.] overall diameter. If a drum is recon­
ditioned in this manner, either the correct factory-
supplied, oversize lining .030"
[0,762
mm.] must be
installed or a shim equal in thickness to the metal
removed must be placed
between
the lining and

shoe
so that the arc of the lining
will
be the same
as that of the drum.

If
it is found when
wheels
are removed that there
is brake fluid leakage at any of the wheel cylinders, it
will
be necessary to replace or recondition the
wheel cylinder (Par. P-21) and bleed the brake lines (Par. P-7).
Whenever the brake lining is replaced in one front
or one rear wheel, be sure to perform the same
operation in the
opposite
front or rear wheel, us­
ing the same brake lining part number. Otherwise, unequal brake action
will
result.

P-22. TROUBLE
SHOOTING

P-23.
Squeaky
Brakes

In
most cases, squeaks are entirely eliminated by

correct
adjustment of the brakes. Squeaks may be
caused however, by glazed linings, lining wore thin
to the point of
exposed
rivets or by vibration. A

drum
will
not vibrate when the brake is securing

uniform
contact over the entire lining surface, ex­
cept when due to improper conditions such as the
linings becoming glazed.
Glazed
surface of the

brake
linings may be removed by a stiff
wire
brush.
Occasionally
squeaks are caused by roughened
sur­

face of the
drum,
which can usually be remedied
by rubbing down with emery cloth and by wiping
the brakings surface clean. In extreme cases it may
be necessary to reface the drum in a lathe. Should
this be done, do not remove a metal thickness greater than .030" [0,762 mm.] - .060" [1,52 mm.]

overall
diameter.

P-24. Rattles
in
Brakes

See that the tension of the springs in the brakes

and
attached to the control system are sufficient to

return
brakes and brake mechanism to their normal
position.
Return
springs are so placed that they
keep all slack out of the control system by tension on all joints.

Brakes
will
not rattle inside the
drum
if the springs
holding the
shoes
are kept at the proper tension. 333
