OB-6 MAINTENANCE AND LUBRICATION
BRAKE SYSTEMS OPERATION
Watch for the "BRAKE" light coming on. Other
signs of possible brake trouble are such things as
repeated pulling to one side when braking, unusual
sounds
when braking or between brake
applications,
or increased brake pedal travel. If you
note one of these conditions, repair the system at
once.
For convenience, the
following should be done
when wheels are removed for rotation: Inspect lines
and hoses
for proper hookup, bindings, leaks, crack,
chafing etc.
Inspect disc brake pads for wear and
rotors
for surface condition.
Inspect other brake parts, including parking brake
drums, linings etc., at the same time. Check parking
brake adjustment.
Inspect brakes more often if habit or
conditions
result in frequent braking.
PARKING BRAKE AND TRANSMISSION
PARK MECHANISM OPERATION
Park on a fairly steep hill and hold the vehicle with
the parking brake only. This checks holding ability.
On
automatic transmission vehicles, shifting from
"P" position to the other positions cannot be made
unless
the brake pedal is depressed when the key
switch is in
"ON" position or the engine running.
WARNING
•
Before checking starter safety switch
operation below,
be sure to have enough
room around the
vehicle. Then firmly apply
both the parking brake and the regular brake.
Do not
use the accelerator pedal. If the engine
starts, be ready
to turn off the key promptly.
Take these precautions because the vehicle
could move
without warning and possibly
cause personal injury
or property damage.
STARTER SAFETY SWITCH OPERATION
(AUTOMATIC TRANSMISSION)
Check by trying to start the engine in each gear
while setting the parking brake and the foot brake.
The starter
should crank only in "P" (Park) or "N"
(Neutral).
STARTER SAFETY SWITCH OPERATION
(MANUAL TRANSMISSION)
To check, place the shift lever in "Neutral", push
the clutch pedal halfway and try to start. The starter
should not crank. The starter should crank only
when the clutch pedal is fully depressed.
ACCELERATOR LINKAGE LUBRICATION
Lubricate the accelerator pedal fulcrum pin with
chassis grease.
STEERING AND SUSPENSION
INSPECTION
Inspect front and rear suspension and steering
system
for damaged, loose or missing parts or signs
of wear. Inspect power steering lines and hoses for
proper hookup, binding, leaks, cracks, chafing, etc.
BODY AND CHASSIS LUBRICATION
Lubricate the key lock cylinders, the hood latch, the
hood and door hinges, the door check link, the
parking cable guides,
the underbody contact points,
and the linkage.
PROPELLER SHAFT INSPECTION AND
LUBRICATION
Lubricate sliding yoke and universal joints with
grease containing MOS2 (disulfide molybdenum
type grease) at the interval shown in the
Maintenance Schedule. Check for play in normal
direction of rotation of sliding yoke and universal
joints. Also check
propeller shaft flange-to-pinion
bolts for proper torque of 63 N·m (46 lb·ft) for front
and rear propeller shaft.
AUTOMATIC TRANSMISSION FLUID
INSPECTION
Check the lubricant level every 7,500 miles (12,000
km) and add lubricant
if necessary.
Under harsh operating conditions, such as constant
driving in heavy city traffic during
hot weather, or in
hilly or mountainous terrain, change the transmission
fluid and service the
sump filter after every 20,000
miles (32,000 km) of operation.
AUTO CRUISE CONTROL INSPECTION
Check to see if the clearance between cruise link and
accelerator is normal. Also check that the vacuum
hoses are routed and connected properly.
CLUTCH LINES AND HOSES INSPECTION
Check lines and hoses for proper attachment,
binding, leaks, cracks, chafing, deterioration, etc.
Any questionable parts should be replaced or
repaired at once. When abrasion or wear is evident
on lines or hoses, the cause must be corrected.

Perform system leak test.
• Charge the system with approx. 200 g (0.44
lbs) of HFC-134a.
• Make sure the high pressure valve of the
manifold gauge is closed.
• Check
to ensure that the degree of pressure
does
not change.
• Check for refrigerant leaks by using a HFC-
134a leak detector.
• If a leak occurs, recover the refrigerant. Repair
the leak, and start all over again from the first
step of evacuation.
If no leaks are found, continue charging re
frigerant to the air conditioning system.
• Charge the refrigerant until the scale reading
decreases
by the amount of the charge
specified.
Specified
amount g (lbs.) I 750 (1.65)
• If charging the system becomes difficult:
( 1) Run the engine at idle and close all the
vehicle doors.
(2) Turn A!C switch "ON".
(3) Set the fan switch to its highest position.
(4) Set air source selector lever to "CIRC".
(5) Slowly open the low side valve on the
manifold gauge set.
WARNING: BE ABSOLUTELY SURE NOT TO
OPEN THE HIGH PRESSURE VALVE OF THE
MANIFOLD GAUGE. SHOULD THE HIGH
PRESSURE VALVE BE OPENED, THE HIGH
PRESSURE REFRIGERANT WOULD FLOW
BACKWARD, AND
THIS MAY CAUSE THE
REFRIGERANT CONTAINER TO BURST.
8. When finished with the refrigerant charging,
close the low pressure valve of the manifold
gauge and container valve.
9. Check for refrigerant leaks.
AIR CONDITIONING 18 -23
Checking
the A/C system
1. Run the engine and close all the vehicle doors.
2. Turn A!C switch "ON", set the fan switch to its
highest position, set air source
lever to "CIRD"
and set temperature lever to full cool position.
3. Check the high and low pressure of the manifold
gauge.
• Immediately after charging refrigerant, both
high and low pressure are slightly high, but
they settle down to the pressure guidelines
shown below:
Ambient temperature: 25-30°C (77 -86°F)
Pressure guidelines:
• High-pressure side;
Approx. 1372.9-1863.3kPa (199.1-270.2psi)
• Low-pressure side;
Approx. 147.1-294.2 kPa (21.3-42.7 psi)
• If an abnormal pressure is found, refer to
"CHECKING REFRIGERANT SYSTEM WITH
MANIFOLD
GAUGE" in this section.
4. Put your hand in front of the air outlet and move
the temperature control lever of the control
panel
to different positions. Check if the outlet
temperature changes as selected by the control
knob.

REPLACEMENT
UNIT REPAIR
WHEELS
REPLACEMENT
When replacement is necessary, the original metric
the size should be used. Most metric tire sizes do not
have exact corresponding alphanumeric tire sizes. It
is recommended that new tires be installed in pairs on
the same axle. If necessary to replace only one tire, it
should be paired with tire having the most tread, to
equalize braking traction.
w CAUTION:
Do not mix different types of tires such as radial,
bias and bias-belted tires except in emergencies,
because
vehicle handling may be seriously
affected and may result in loss of control.
TIRE DISMOUNTING
Remove valve cap on valve step and deflate the tire.
Then use a
tire changing machine to mount or
dismount tires.
Follow the equipment manufacturer's instruction. Do
not use hand tools or tire lever alone to change tires
as they may damage the tire beads or wheel rim.
TIRE MOUNTING
Rim bead seats should be cleaned with a wire brush
....._., or coarse steel wool to remove lubricants, and light
rust. Before mounting a tire, the bead area should be
well lubricated with an approved tire lubricant.
After mounting, inflate the tire to 196kPa (28 psi) so
that beads are completely seated. Inflate the air to
specified pressure and install valve cap to the stem.
\f WARNING:
Never stand over tire when inflating. Bead may
break when bead snaps over rim's safety hump
and cause serious personal injury.
Never exceed
240 kPa (35 psi) pressure when
inflating. If 240 kPa (35 psi) pressure will not
seat beads, deflate, re-lubricate and re-inflate.
Over
inflation may cause the bead to break and
cause serious
personal injury.
TIRE REPAIR
There are many different materials on the market
used to repair tires.
Manufacturers have published detailed instructions
on how and when to repair tires. These instructions
can be obtained from the tire manufacturer if they are
not included with the repair kit. Damaged
wheels and wheels with excessive run-out
must be replaced.

SA-2 HYDRAULIC BRAKES
BRAKE SYSTEM DIAGNOSIS
ROAD TESTING THE BRAKES
Brake Test
Brakes should be tested on a dry, clean, reasonably
smooth and
level roadway. A true test of brake
performance cannot be made
if the roadway is
wet, greasy
or covered with loose dirt so that all
tires do not grip the road equally. Testing will also
be adversely affected if the roadway is crowned so
as to throw the weight of the vehicle toward
wheels on one side or if the roadway is so rough
that wheels tend to bounce. Test the brakes at dif
ferent vehicle speeds with both light and heavy
pedal pressure; however, avoid locking the wheels
and sliding the tires. Locked wheels and sliding
tires do not indicate brake efficiency, since heavily
braked but turning wheels will stop the vehicle in
less distance than locked wheels. More tire-to-road
friction is present
with a heavily braked turning tire
then
with a sliding tire.
The standard brake system is designed and
balanced
to avoid locking the wheels except at very high
deceleration
levels.
It
is designed this way because the shortest stopping
distance and best
control is achieved without brake
lock-up.
Because of high deceleration capability, a firmer pedal
may be felt at higher deceleration levels.
External Conditions That Affect Brake
Performance
1.
2.
3.
Tires: Tires having unequal contact and grip on
the road
will cause unequal braking. Tires must
be equally inflated, identical in size, and the tread
pattern
of right and left tires must be approxi
mately equal.
Vehicle loading:
A heavily loaded vehicle requires
more braking effort.
Wheel Alignment: Misalignment of the wheels,
particularly
in regard to excessive camber and
caster,
will cause the brakes to pull to one side.
BRAKE FLUID LEAKS
With engine running at idle and the transmission in
"Neutral", depress the brake pedal and hold a constant
foot pressure on the pedal. If pedal gradually falls
away with the constant pressure, the hydraulic system
may be leaking.
Check the master cylinder fluid level. While a slight
drop in reservoir level will result from normal lining
wear, an abnormally low level in reservoir indicates a
leak in the system. The hydraulic system may be
leaking internally as well as externally. Refer to
"Master Cylinder Inspection". Also, the system may
appear
to pass this test but still have slight leakage. If
fluid level
is normal, check the vacuum booster
push rod
length. If an incorrect length push rod is
found, adjust
or replace the push rod. Check the
brake
pedal travel and the parking brake adjust
ment.
When checking the
fluid level, the master cylinder fluid
level
may be low from the "MAX" mark if the front and
rear
linings are worn. This is not abnormal.
WARNING LIGHT OPERATION
When the ignition switch is in the START position,
the
"BRAKE" warning light should glow and go off
when the ignition switch returns to the ON position.
The
following conditions will activate the "BRAKE"
light:
1. Parking brake applied. The light should be on
whenever the parking brake is applied and the
ignition switch is on.
2. Low fluid level. A low fluid level in the master
cylinder will turn the "BRAKE" light on (Except
Rear
Wheel Antilock Brake System (RWAL)
model).
3. During engine cranking the "BRAKE" light
should
remain on. This notifies the driver that
the warning circuit is operating properly.
4. In the event of a front or rear system malfunc
tion (RWAL model only).
5. In the event of RWAL malfunction (RWAL
model only. Refer to Section 5A3).
ANTILOCK BRAKE SYSTEM (RWAL or
ABS}
Refer to Section 5A3 or 5A4 for inspection and di
agnosis procedure of the hydraulic unit.
