DIAGNOSIS
STABILIZER BAR AND/OR BUSHING CHECK
Bar
Inspect for damage or deformation.
If defective, replace.
Bushing
Inspect for damage, wear or deterioration.
If defective, replace.
STRUT ASSEMBLY CHECK
Inspect strut for oil leakage, damage or deformation.
If strut is found faulty, replace it as an assembly unit,
because it can not be disassembled.
Inspect strut function refer to the following procedures.
1) Check and adjust tire pressures as specified.
2) Bounce vehicle body 3 or 4 times continuously by pushing
front end on the side with strut to be checked.
3) Apply the same amount of force at each push and note strut
resistance both when pushed and rebounding.
4) Also, note how many times vehicle body rebounds before
coming to stop after hands are off. Do the same for strut on
the other side.
5) Compare strut resistance and number of rebalance on the
right with those on the left. And they must be equal in both.
With proper strut, vehicle body should come to stop the
moments hands are off or after only one or two small rebal-
ances.
If conditions of struts are in doubt, compare them with known-
good vehicle or strut.
Inspect bearing for wear, abnormal noise or gripping.
If defective, replace.

3E-4 REAR SUSPENSION
DIAGNOSIS
REAR SHOCK ABSORBER CHECK
Inspect for deformation or damage.
Inspect bushings for wear or damage.
Inspect for evidence of oil leakage.
Replace any defective part.
TRAILING ARM, LATERAL ROD, REAR AXLE,
PEAR AXLE HOUSING AND COIL SPRING
CHECK
Inspect for cracks, deformation or damage.
Inspect bushing for damage, wear or breakage.
Replace any defective part.WARNING:
When handling rear shock absorber (1) in which high-
pressure gas is sealed, make sure to observe the follow-
ing precautions.
Don’t disassemble it.
Don’t put it into the fire.
Don’t store it where it gets hot.
Before disposing it, be sure to drill a hole (approxi-
mately 3 mm (0.12 in.) diameter) (2) in it where shown
by an arrow in figure and let gas and oil out.
Lay it down sideways for this work. The gas itself is
harmless but it may issue out of the hole together with
chips generated by the drill. Therefore, be sure to wear
goggle.

22) Upon completion of all jobs, pull parking brake lever with
about 20 kg, (44 lbs) load three to five times so as to obtain
proper drum-to-shoe clearance.
Adjust parking brake cable (for adjustment, see Section 5.)
23) Lower hoist.
24) Tighten right and left trailing arm bolts and nuts (1) and
shock absorber lower bolts (2) to specified torque.
Tighten lateral rod bolt and nut (3) to specified torque.
Tightening torque
Rear trailing arm bolts (a) : 80 N·m (8.0 kg-m, 58.0 lb-ft)
Rear shock absorber lower bolts
(b) : 58 N·m (5.8 kg-m, 42.0 lb-ft)
Lateral rod axle housing side nut
(c) : 50 N·m (5.0 kg-m, 36.5 lb-ft)
Lateral rod body side nut (d) : 65 N·m (6.5 kg-m, 47.0 lb-ft)
25) Check to ensure that brake drum is free from dragging and
proper braking is obtained.
26) Perform brake test (foot brake and parking brake).
(For brake test, see Section 5.)
27) If equipped with LSPV, check and adjust LSPV spring refer-
ring to “LSPV INSPECTION AND ADJUSTMENT” and per-
form “FLUID PRESSURE TEST” in Section 5.
28) Check each installed part for oil leakage.
NOTE:
When tightening these bolts and nuts, be sure that vehi-
cle is off hoist and in non loaded condition.

5-4 BRAKES
DIAGNOSIS
ROAD TESTING BRAKES
Brakes should be tested on dry, clean, smooth and reasonably level roadway which is not crowned. Road test
brakes by making brake applications with both light and heavy pedal forces at various speeds to determine if the
vehicle stops evenly and effectively. Also drive vehicle to see if it leads to one side or the other without brake
application. If it does, check the tire pressure, front end alignment and front suspension attachments for loose-
ness. See diagnosis table for other causes.
BRAKE FLUID LEAKS
Check the master cylinder fluid levels. While a slight drop in reservoir level does result from normal lining wear,
an abnormally low level indicates a leak in the system. In such a case, check the entire brake system for leak-
age. If even a slight evidence of leakage is noted, the cause should be corrected or defective parts should be
replaced.
SUBSTANDARD OR CONTAMINATED BRAKE FLUID
Improper brake fluid, mineral oil or water in the fluid may cause the brake fluid to boil or the rubber components
in the hydraulic system to deteriorate.
If primary piston cups are swollen, then rubber parts have deteriorated. This deterioration may also be evi-
denced by swollen wheel cylinder piston cups on the drum brake wheels.
If deterioration of rubber is evident, disassemble all hydraulic parts and wash with alcohol. Dry these parts with
compressed air before assembly to keep alcohol out of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads.
If master cylinder piston seals are satisfactory, check for leakage or excessive heat conditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed system.
The system must be flushed if there is any doubt as to the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to contaminated fluid.

5) If rear brake pressure is not within specification, adjust it by
changing bolt (2) position as follows.
If rear brake pressure is higher than specification, move bolt
(2) center side and if it is lower, out side.
Repeat steps 3) and 4) until rear brake pressure is within
specification.
After adjustment, be sure to torque nut (1) to specification.
Tightening torque
LSPV nut (a) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
6) Upon completion of fluid pressure test, bleed brake system
and perform brake test.
MASTER CYLINDER AND BRAKE FLUID
LEVEL INSPECTION
1) Check master cylinder and reservoir tank for crack, damage
and brake fluid leakage. If any faulty condition exists, correct
or replace.
2) Check that brake fluid level is between MAX and MIN marks
on reservoir tank.
2
1, (a)
NOTE:
Be sure to use particular brake fluid either as indicated
on reservoir cap of that vehicle or recommended in
owner’s manual which comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked
on reservoir.
When brake warning lamp lights sometimes during driv-
ing, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake system for
leakage. Correct leaky points and then refill to specified
level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has
been used for mineral oil or a container which is wet from
water. Mineral oil will cause swelling and distortion of
rubber parts in hydraulic brake system and water mixed
into brake fluid will lower fluid boiling point. Keep all fluid
containers capped to prevent contamination.
