(g) Install the parking lock cable No. 2 to column upper brack-
et with the clip.
(h) Install the cable end to the sliding block of the column up-
per bracket with the screw.
Torque: 2.2 N´m (23 kgf´cm, 19 in.´lbf)
(i) After installation, check the following items.
(1) When the pedal button is pushed, shift lever should
be locked.
(2) When the pedal button is released, shift lever
should be unlocked.
4. INSTALL STEERING COLUMN ASSEMBLY
(See page SR±23)
5. ADJUST CABLE HOUSING
(a) Shift the shift lever to the P position.
(b) Turn the ignition key to the LOCK position.
(c) Loosen the 2 bolts and adjust the cable housing.
HINT:

Pedal button should touch the pedal plate cushion.

Brake pedal should not be moved by the pedal button.

Cable housing should not be toughed the brake pedal
and the brake pedal plate cushion.
(d) Torque the 2 bolts.
Torque: 10.5 N´m (110 kgf´cm, 8 ft´lbf)
6. CONFIRM SHIFT LOCK SYSTEM OPERATION
(a) Only when the brake pedal is engaged and the ignition
key is not in the LOCK position, the shift lever can be
shifted from the P position to other positions.
When the shift lever is in the P position and the brake ped-
al is released, the shift lever cannot be shifted from P posi-
tion to other positions.
(b) When the shift lever is not in the P position, the ignition
key cannot be turned to the LOCK position.
Only when the shift lever is in the P position, the ignition
key can be removed.
(c) Cable No. 1 and No. 2 should not be deformed by other
parts located around the steering column.

REMOVAL
1. REMOVE REAR WHEEL
Torque: 110 N´m (1,150 kgf´cm, 83 ft´lbf)
2. DISCONNECT BRAKE LINE
Using SST, disconnect the brake line and remove the clip.
SST 09023±00101
Torque: 15.5 N´m (158 kgf´cm, 11 ft´lbf)
3. REMOVE BRAKE CALIPER AND DISC
Remove the 2 bolts, brake caliper and disc.
Torque: 105 N´m (1,070 kgf´cm, 77 ft´lbf)
4. CHECK BEARING BACKLASH AND AXLE SHAFT
DEVIATION
(a) Using a dial indicator, check the backlash in the bearing
shaft direction.
Maximum: 0.6 mm (0.024 in.)
If the backlash exceeds the maximum, replace the bearing.
(b) Using a dial indicator, check the deviation at the surface
of the axle shaft outside the hub bolt.
Maximum: 0.1 mm (0.0040 in.)
If the deviation exceeds the maximum, replace the axle shaft.
5. REMOVE PARKING BRAKE ASSEMBLY
(a) Remove the parking brake assembly (See page
BR±43).
(b) Remove the 2 bolts and pull out the parking brake cable
from the backing plate.
Torque: 8.0 N´m (82 kgf´cm, 71 in.´lbf)
(c) Use the same procedures described above to the other
side.
