< PERIODIC MAINTENANCE >

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.

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.

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.

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.

- 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

ST-18, "Steering Wheel"

- Neutral position steering wheel, steering wheel turning force, and front wheel turning angle: Refer to

ST-5,
