_ CAUTION
When servicing brake assemblies or components, do not create dust by sanding, grinding or by cleaning
brake parts with a dry brush or with compressed air. A WATER DAMPENED CLOTH SHOULD BE USED.
Many brake components contain asbestos fibers which can become air-borne if dust is created duringservice operations. Breathing dust which contains asbestos fibers can cause serious bodily harm.

BLEEDINGN65FYAN
When the master cylinder is empty of brake fluid, bleed air
from the master cylinder by proceeding with procedures (1)
thru (6). (Because this master cylinder is not equipped with a
check valve.)
When brake fluid remains in the master cylinder, proceed with
step (6).
(1) -Disconnect the brake tube from the master cylinder.
(2) Two persons should conduct the air bleeding, one person
slowly depressing the brake pedal and holding the pedal
depressed.(3) In this condition, the other person should use a finger to
close the outlet part of the master cylinder, and then the
first person should release the brake pedal.
(4) Steps (2) and (3) should be repeated three or four times,
and then the master cylinder should be filled with brake
fluid to the specified level.
NOTE
The air is completely bled from the master cylinder by steps
(1) to (4).
(5) Connect the brake tube to the master cylinder.
(6) Start the engine; then, in the sequence shown in the
illustration, bleed the air from each wheel cylinder.
Specified brake fluid: MOPAR Brake Fluid/
Conforming to DOT3
Caution
1.Use the specified brake fluid. Avoid using a mixture
of the specified brake fluid and other fluid.2. If brake fluid is exposed to the air, it will absorb
moisture; as water is absorbed from the atmos-phere, the boiling point of the brake fluid will
decrease and the braking performance will be
seriously impaired. For this reason, use a hermeti-
cally sealed 1 lit.
(1.06 qt.) or 0.5 lit. (0.52 qt.) brake
fluid container.3. Firmly close the cap of the brake fluid container
after use.
4. For vehicles with the anti-lock braking system, besure to install a filter to the master cylinder
reservoir tank when supplying brake fluid.
ORDINARY AIR-BLEEDING PROCEDURES(1) Depress the brake pedal several times until resistance is
felt; then, with the pedal depressed, loosen the bleeder
screw
l/3 to l/2 turn and then tighten it before the fluid
pressure is all gone.
(2) Release the brake pedal. Repeat this procedure until there
are no more air bubbles in the brake fluid.

servicing clutch assemblies or com-
ponents for vehicles with 1.8L engine, doNOT
create dust by sanding or by cleaning
clutch parts with a dry brush or with
compressed air. (A water dampened cloth
should be used). The clutch disc contains
“Asbestos Fibers” which can become air-
borne if dust is created during serviceoperations. Breathing dust containing
“Asbestos Fibers”may cause seriousbodily
harm.

5.If the clutch pedal free play and the distance between the
clutch pedal and the firewall when the clutch is disengageddo not agree with the standard values, it is probably the
A
result of either air in the hydraulic system or a faulty master2
cylinder or clutch. Bleed the air, or disassemble and inspectthe master cylinder or clutch.
BLEEDINGWhenever the clutch tube, the clutch hose, and/or the clutch
master cylinder have been removed, or if the clutch pedal is
spongy, bleed the system.
Caution
Use the specified fluid. Avoid using a mixture of the
specified fluid and other fluid.

V-BELT TENSION CHECKNlSFliAl
1.Check to be sure that the belt is not damaged and that the
V-belt is correctly attached to the groove of the pulley.
NOTE, If there is abnormal noise or belt slippage, check the belt
tension and check for unusual wear or abrasion, or damage,
of the
pullev contact surface, and for scars or scratches onthe
pulley.2.
Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value: 6-9 mm
1.26.35 in.)
3. If there is a deviation from the standard value range, make
an adjustment of the belt tension by following the procedures
described below.
(1) Loosen bolts A, B and C (for holding the oil pump).
(2) Place a bar or similar object against the body of the oil
pump, and, while manually providing the suitable
amount of tension, adjust the amount of
flexion of the
belt.
(3) Tighten bolts A, B and C (for holding the oil pump).
(4) Check the amount of flexion of the belt; readjust if
necessary.
CautionThe check should be made after turning the engine
one time or more in the regular direction of rotation (tothe
dght).
FLUID LEVEL CHECKNlSFIAI
1.Park the vehicle on a flat, level surface, startthe engine, andthen turn the steering wheel several times to raise the
temperature of the fluid to approximately
50-60°C
(122-140°F).2. With the engine running, turn the wheel all the way to the
left and right several times.3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTNlSFJAJ
1.Raise the front wheels on a jack, and then support them with
rigid racks.2. Disconnect the return hose connection.
3.Connect a vinyl hose to the return hose, and drain the oil into
a container.

STEERING - Service -Adjustment Procedures < Power Steering >IgJf~
4.Disconnect the high-tension cable, and then while operating
the starting motor intermittently, turn the steering wheel all;
the way to the left and right several times to drain all of the
fluid.
Caution, 35
Be careful not to position thq high-tension able ye&r the
carburetor or the delivery pipe.5. Connect the return hoses securely, and then
secur& it ,with
the clip.6. Fill the oil reservoir with the specified fluid up
td the Ibwerposition of the filter, and then bleed the air.

BLEEDINGNlSFKAG
1.Jack up the front wheels and support them by using a floor
stand.2. Manually turn the oil pump pulley a few times.
3. Turn the steering wheel all the way to the left and right
several times.
4.Disconnect the high-tension cable, and then, while operatingthe starting motor intermittently, turn the steering wheel all
the way to the left and right several times
(for 1-5 to 20
seconds).
Caution
1. During air bleeding, replenish the fluid supply so thatthe level never falls below the lower positiin
@f the
eiter.I .“:
2. If air bleeding is done while engine is runnind, ‘the air
will be
brokeir up and absorbed intti the fluid;‘?ti’ sureto do the bleeding only while cranking.
5.Connect the ignition cable, and then start the engine (idling).6. Turn the steering wheel to the left and right until there are
no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the level is
upito the specified position on the level gauge.
8.Confirm that there is very little change in the fluid level whenthe steering wheel is turned left and right.
9.Check whether or not the change in the fluid level is within5 mm
(.2 in.) when the engine is stopped and when it is
running.
Caution
1.If the change of the fluid level is 5 mm I.2 in.) or more,
the air has not been completely bled from the system,
and thus must be bled completely.2. If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled.
3. If air bleeding is not complete, there will be abnormal
noises from the pump and the flow-control valve, and
this
condition could cause a lessening of the life of the
pump, etc.
