2) Visually check the pad thickness through inspec-
tion hole of disc brake assembly. Replace the pad if
necessary.

for both the right and left wheels at the same
time. Also replace the pad clips if they are twist-
ed or worn.3) Check the disc rotor, and correct or replace if it is
damaged or worn.

Brake Linings and Drums
21.Brake Linings and Drums
A: INSPECTION
1. REAR DRUM BRAKE
1) Remove the brake drum, and check that there is
no fluid leakage from wheel cylinder.
If there is fluid leakage from wheel cylinder, inspect
the wheel cylinder, and then repair or replace it.
2) Inspect the brake shoes for damage or deformi-
ties and check brake linings for wear.
CAUTION:
 Always replace both leading and trailing
brake shoes for the right and left wheels at the
same time.
 When either the right and left brake assembly
is replaced, always replace the leading shoe
and trailing shoe of the other.
Thickness of lining (except back metal)
Standard value: 4.1 mm (0.161 in)
Service limit: 1.5 mm (0.059 in)
3) Check the brake drum for wear, dents or other
damage.
If the inside surface of brake drum is streaked, cor-
rect the surface with emery cloth (#200 or more). If
it is unevenly worn, tapered or the outside surface
of brake drum is damaged, correct or replace it.
Brake drum inner diameter
Standard value: 228.6 mm (9.000 in)
Service limit: 230.6 mm (9.079 in)If deformation or wear of back plate, shoe, etc. is
noticeable, replace the affected parts.
2. PARKING BRAKE (REAR DISC BRAKE)
Inspect the brake linings and the disk rotor inside of
both sides of the rear brake at the same time by re-
moving the disk rotor.
1) Inspect the brake shoes for damage or deforma-
tion and check brake linings for wear.
CAUTION:
Always replace both primary and secondary
brake shoes for the right and left wheels at the
same time.

2) Check the disk rotor for wear, dents or other
damage. If the inside surface of disk rotor is
streaked, correct the surface with emery cloth
(#200 or more). If it is unevenly worn or tapered,
correct or replace it.
Brake drum inside diameter
Standard value: 170 mm (6.69 in)
Wear limit: 171 mm (6.73 in)
3) If the deformation or wear of back plate, shoe,
etc. is noticeable, replace them.
4) When the shoe return spring tension is exces-
sively weakened, replace it.B: ADJUSTMENT
1. REAR DRUM BRAKE
The main brake is adjusted automatically, and so
there is no need to adjust it.
2. PARKING BRAKE (REAR DISC BRAKE)
For rear disc brake, adjust the parking brake after
bleeding air.
1) Remove the rear cover (rubber) installed at back
plate.
2) Turn the adjuster toward arrow mark (upward)
until it is locked slightly, by using a flat tip screwdriv-
er as shown in illustration.
3) Turn back (downward) the adjuster 3 to 4 notch-
es.
4) Install the rear cover (rubber) at original position
correctly.

Suspension
22.Suspension
A: INSPECTION
1. SUSPENSION BALL JOINT
1) Jack-up the vehicle until front wheels are off
ground.
2) Grasp the bottom of tire and move it in and out.
If relative movement (B) is observed between the
brake disc cover (A) and end of transverse link (D),
ball joint (C) may be excessively worn.
3) Grasp the end of transverse link (C) and move it
up and down. Relative movement (A) between the
housing (D) and transverse link boss indicates ball
joint (B) may be excessively worn.
4) If relative movement is observed in the immedi-
ately preceding two steps, remove and inspect the
ball joint. If free play exceeds standard, replace the
ball joint.
5) Damage of dust seal
Visually inspect the ball joint dust seal. If it is dam-
aged, remove the transverse link. Front Transverse Link.> And measure free play of
ball joint.
(1) When looseness exceeds standard value,
replace the ball joint.
(2) If the dust seal is damaged, replace with the
new ball joint.
NOTE:
When the transverse link ball joint has been re-
moved or replaced, check the toe-in of front wheel. If the front wheel toe-in is not at specified value, ad-
just the toe-in.
2. TRANSVERSE LINK’S REAR BUSHING
Check oil leaks at around liquid-filled bushing. If oil
leaks, replace the bushing.
3. WHEEL ARCH HEIGHT
1) Unload cargoes and set the vehicle in curb
weight (empty) condition.
2) Then, check the wheel arch height of front and
rear suspensions to ensure that they are within
specified values.
3) When the wheel arch height is out of standard,
visually inspect the following components and re-
place deformed parts.
 Suspension components [Front strut assembly
and rear strut assembly]
 Parts connecting between suspension and body.
4) When no components are deformed, adjust the
wheel arch height by replacing coil spring in the
suspension which wheel arch height is out of stan-
dard. RS-8, Wheel Alignment.>

sion before removal, installation or disassembly.
 Keep the disassembled parts in order and pro-
tect them from dust or dirt.
 Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly, and replacement. Be careful not to burn yourself, because each
part on the vehicle is hot after running.
