Diagnosis
Diagnosis Table
Refer to “Diagnosis Table” in Section 3.
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, Axle Housing and
Coil Spring Check
Inspect for cracks, deformation or damage.
Replace any defective part.
Trailing Arm and Lateral Rod Bush Check
Inspect for wear and breakage. If found defective, replace.WARNING:
When handling rear shock absorber in which high-pres-
sure gas is sealed, make sure to observe the following
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 in it where
shown by an arrow in the 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. There-
fore, be sure to wear goggle.
A : Drill hole with approximately 3 mm (0.12 in.) diameter.

ing Torque Specifications” of this section.
Bearing Retainer and Axle Shaft Oil Seal
Check
When brake drum has been removed, check inside of brake
drum for gear oil leakage.

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 looseness. 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.
If fluid level is lower than the minimum level of reservoir, refilling is necessary. Fill reservoir with specified brake
fluid.
Brake fluid: Refer to reservoir tank cap.
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 linings.
If master cylinder piston seals are satisfactory, check for leakage or excessive heat conditions. If condition is not
found, drain fluid, flush with brake fluid, refill and bleed the 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.CAUTION:
Since brake system of this vehicle is factory-filled with brake fluid indicated on reservoir tank cap, do
not use or mix different type of fluid when refilling; otherwise serious damage will occur.
Do not use old or used brake fluid, or any fluid from a unsealed container.

Rear Drum Brake Shoe Adjustment
Rear brake has self-adjusting mechanism but it does require
adjustment for proper drum to shoe clearance when brake shoe
has been replaced or brake drum has been removed for some
other service.
Adjustment is automatically accomplished by depressing brake
pedal about 30 times with approximately 30 kg (66 Ibs) load after
all parts are installed.
Then check brake drum for dragging and brake system for proper
performance. After lowering vehicle from hoist, brake test should
be performed.
Parking Brake Inspection and Adjustment
INSPECTION
Hold center of parking brake lever grip and pull it up with 20 kg
(44 Ibs) force.
With parking brake lever pulled up as above, count ratchet
notches.
There should be 6 to 8 notches.
Also, check if both right and left rear wheels are locked firmly. To
count number of notches easily, listen to click sounds that ratchet
makes while pulling parking brake lever without pressing its but-
ton.
One click sound corresponds to one notch.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.
