5. Start wheel balancer. Make sure that inner and outer residual imbalance values are 5 g (0.18 oz) each or
below.
Wheel Balance (Maximum Allowable Imbalance)
• If either residual imbalance value exceeds 5 g (0.18 oz), repeat installation procedures.
Tire RotationINFOID:0000000003533885
1. Rotate the tires on each side from front to back as shown.
2. Adjust the tire pressure to specification. Refer to WT-28, "
Tire" .
3. After the tire rotation, retighten the wheel nuts after the vehicle
has been driven for 1,000 km (600 miles), and also after a wheel
and tire have been installed such as after repairing a flat tire.
Checking Brake Fluid Level and LeaksINFOID:0000000003533886
• Check the brake fluid level in the reservoir tank. It should be
between the “MAX” and “MIN” lines on the reservoir tank.
• If the fluid level is extremely low, check the brake system.
• If the brake warning lamp comes on when the fluid is at the correct
level, check the brake fluid level switch and the parking brake
switch.
CheckingBrake Line and CablesINFOID:0000000003533887
1. Check the brake lines and hoses for cracks, deterioration, and
other damage. Replace any damaged parts.
CAUTION:
If brake fluid leaks are visible around the brake line joints,
retighten the joint, or replace damaged parts as necessary.
2. Check for brake fluid leaks by fully depressing brake pedal while
engine is running.

• Check the power steering fluid level with the engine off.
• Check fluid level on reservoir. Use “HOT” range at fluid tempera-
tures of 50° to 80°C (122° to 176°F). Use “COLD” range at fluid
temperatures of 0° to 30°C (32° to 86°F).
CAUTION:
• Do not overfill.
• Refer to MA-10, "
Fluids and Lubricants" .
CHECKING LINES
• Check lines for improper attachment, leaks, cracks, damage, loose
connections, chafing, and deterioration.
Checking Axle and Suspension PartsINFOID:0000000003533891
FRONT AND REAR AXLE AND SUSPENSION PARTS
Check front and rear axle and suspension parts for excessive play, cracks, wear or other damage.
• Shake each wheel to check for excessive play.
• Rotate each wheel to check for abnormal noise.
• Check the axle and suspension nuts and bolts for looseness.
• Check the strut and shock absorber for oil leakage or other damage.
• Check the suspension ball joints for grease leakage and ball joint dust cover for cracks or other damage.
DRIVE SHAFT
Check the boots and drive shaft for cracks, wear, damage, and
grease leakage.

PEDAL STROKE
• When parking brake pedal is operated with the specified force, make sure the stroke is within the specified
number of notches. Check by listening and counting the ratchet clicks.
INSPECTION
• Make sure the components are attached properly, checking for looseness or backlash.
• Check parking brake pedal assembly for bends, damage and cracks, and replace if necessary.
• Check cable for wear and damage, and replace if necessary.
• Check parking brake warning lamp switch for malfunction, and replace if necessary. Refer to DI-27, "
Wiring
Diagram - WARN -".
ADJUSTMENT
1. Remove the lower instrument panel LH. Refer to IP-10, "Removal and Installation" .
2. Partially engage parking brake pedal to access adjusting nut.
3. Insert a deep socket wrench to rotate adjusting nut and loosen
cable sufficiently. Then, disengage the parking brake pedal.
4. Remove the wheel and tire using power tool.
5. Remove the disc rotor and measure inner diameter at widest
point using Tool.
6. Transfer measurement less 0.6 mm to the parking brake shoes
and adjust accordingly.
7. Using wheel nuts, secure the disc to the hub to prevent it from
tilting.
8. Rotate the disc rotor to make sure there is no drag.
9. Adjust cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg-f,
110 lb-f).
b. Rotate adjusting nut with deep socket to adjust pedal stroke to
specification.
c. With parking brake pedal completely disengaged, make sure
there is no drag on the parking brake.
10. Install the disc rotor.
11. Install the wheel and tire using power tool.
12. Install the lower instrument panel LH. Refer to IP-10, "
Removal and Installation" . Pedal stroke : 3 − 4 notches [under force of 196 N (20.0 kg-f, 44.1 lb-f)]
