NOTE:
There are 2 types of oil seal ((1) & (2)). Their shapes are dif-
ferent as shown in the figure but they are both usable.
Special Tool (B) can be used for both oil seals (1) and (2).
Make sure that oil seal is free from inclination as it is
installed.
Refer to the figure to check that oil seal is installed in
proper direction.
CAUTION:
When installing oil seal (2), never hit any part other than
the position indicated as (6) in the figure. Make sure to
use special tools indicated below. Failure to observe this
caution will cause oil seal to be deformed and oil leakage
to occur.

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.

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.

8) After completing installation, fill reservoir with brake fluid and
bleed air from brake system. Perform brake test and check
each installed part for oil leakage.
BRAKE DISC
REMOVAL
1) Hoist vehicle and remove wheel.
2) Remove caliper assembly by removing caliper carrier bolts
(2 pcs)
3) Pull brake disc off by using 8 mm bolts (1) (2 pcs).WARNING:
Make sure that flexible hose is not twisted when tighten-
ing joint bolt. If it is twisted, reconnect it using care not to
twist it.
CAUTION:
During removal, be careful not to damage brake flexible
hose and not to depress brake pedal.
NOTE:
Hang removed caliper with a wire hook or the like so as
to prevent brake hose from bending and twisting exces-
sively or being pulled.
Don’t operate brake pedal with brake pads removed.

b) For 4WD vehicle :
Pull brake drum off by using 8 mm bolts.
INSPECTION
Brake Drum
Inspect brake drum for wear.
If limit value of drum inner diameter is exceeded or uneven or
stepped wear is excessive, replace drum.
Drum inner diameter “a”
Standard : 180 mm (7.09 in.)
Limit : 182 mm (7.17 in.)
Brake Shoe
Measure thickness of brake shoe (1) (not including backing
metal). Also, check surface of lining for hardening, excessive
wear and oil.
Brake shoe thickness
Standard : 3.9 mm (0.15 in.)
Limit : 1.0 mm (0.04 in.)
NOTE:
When drum is removed, visually inspect wheel cylinder
for brake fluid leakage. Correct leaky point, if any.
CAUTION:
Never polish lining with sandpaper. If lining is polished
with sandpaper, hard particles of sandpaper will be
deposited in lining and may damage drum. When it is
required to correct lining, replace it with a new one.
