Check the thickness of the disc rotor using a micrometer. Replace
the disc rotor if the thickness is below the wear limit.
FRONT DISC BRAKE : Brake Burnishing
INFOID:0000000009756209
CAUTION:
• Burnish contact surfaces between brake pads and disc rotor according to the following procedure
after refinishing the disc rotor, replacing brake pads or if a soft pedal occurs at very low mileage.
• Be careful of vehicle speed. Brakes do not operate firmly/securely until pads and disc rotor are
securely seated.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive the vehicle on straight, flat road.
2. Depress the brake pedal until the vehicle stops.
3. Release the brake pedal for a few minutes to allow the brake components to cool.
4. Repeat steps 1 to 3 until pad and disc rotor are securely seated.

INSPECTION
Appearance
Check surface of brake drum for uneven wear, cracks and serious damage. Replace it if necessary. Refer to
BR-42, "Removal and Installation"
.

CHASSIS AND BODY MAINTENANCE
Check inner diameter (B) of the brake drum using suitable tool.
REAR DRUM BRAKE : Brake Burnishing
INFOID:0000000009756212
CAUTION:
• Burnish contact surfaces between brake drum and brake lining according to the following procedure
after refinishing or replacing brake drum, or if a soft pedal occurs at very low mileage.
• Be careful of vehicle speed because the brake does not operate firmly/securely until brake drum and
brake lining are securely fitted.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive the vehicle on straight, flat road.
2. Depress the brake pedal until the vehicle stops.
3. Release the brake pedal for a few minutes to allow the brake components to cool.
4. Repeat steps 1 to 3 until pad and disc rotor are securely seated.
REAR DISC BRAKE

PAD WEAR
Check pad thickness from an inspection hole on caliper body. Check
using a scale if necessary.

INFOID:0000000009756214
APPERANCE
Check surface of disc rotor for uneven wear, cracks or damage. Replace if any abnormal conditions exist.
RUNOUT
1. Check the wheel bearing axial end play before the inspection. Refer to
Brake drum inner diameter (B) : Refer to

2. Secure the disc rotor to the wheel hub and bearing assembly
with wheel nuts at two wheel nut locations.
3. Inspect the runout with a dial gauge, measured at 10 mm (0.39
in) inside the disc edge.
4. Find the installation position with a minimum runout by shifting
the disc rotor-to-wheel hub and bearing assembly installation
position by one hole at a time if the runout exceeds the limit
value.
5. Refinish the disc rotor if the runout is outside the limit even after performing the above operation. When
refinishing, use Tool.
Thickness
Check the thickness of the disc rotor using a micrometer. Replace
the disc rotor if the thickness is below the minimum thickness.
REAR DISC BRAKE : Brake Burnishing
INFOID:0000000009756215
CAUTION:
• Burnish contact surfaces between brake pads and disc rotor according to the following procedure
after refinishing the disc rotor, replacing brake pads or if a soft pedal occurs at very low mileage.
• Be careful of vehicle speed. Brakes do not operate firmly/securely until pads and disc rotor are
securely seated.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive the vehicle on straight, flat road.
2. Depress the brake pedal until the vehicle stops.
3. Release the brake pedal for a few minutes to allow the brake components to cool.
4. Repeat steps 1 to 3 until pad and disc rotor are securely seated.
STEERING GEAR AND LINKAGE

INFOID:0000000009756216
INSPECTION AFTER DISASSEMBLY
BOOT
• Check boot for cracks. Replace if any damage is found.
STEERING GEAR ASSEMBLY HOUSING
• Check steering gear assembly housing for damage and scratches. Replace if there are any abnormal condi-
tions.
OUTER SOCKET AND INNER SOCKET
• Ball joint swinging torque

- Hook a spring balance to the ball stud and inner socket measuring
point (*) and pull the spring balance. Make sure that the spring bal-
ance reads the specified value when ball stud and inner socket
start to move. Replace outer socket and inner socket if they are
outside the specification.
• Ball joint rotating torque
- Make sure that the reading is within the following specified range
using Tool (A). Replace outer socket if the reading is outside the
specification.
• Ball joint axial end play
- Apply an axial load of 490 N (50 kg, 111 lb.) to ball stud. Measuring
the amount of stud movement using a dial gauge, make sure that
the value is within specification. Replace outer socket (A) and
inner socket (B) if the measured value is outside specification.
INSPECTION AFTER INSTALLATION
• Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
• Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel
turning angle.
- Steering wheel play: Refer to
- Neutral position steering wheel, steering wheel turning force, and front wheel turning angle: Refer to
