Remove the mounting bolts which hold the speed sensor
bracket to the knuckle, and then remove the speed sensor.Caution
Be careful when handling the pole piece at the tip of
the speed sensor and the toothed edge of the rotor so
as not to damage them by striking against other parts.
5. REMOVAL OF CALIPER ASSEMBLY
Remove the caliper assembly and suspend it with wires.
8. DISCONNECTION OF LOWER ARM BALL JOINT
Using the special tool, disconnect the lower arm ball joint
from the knuckle.
Caution,*1. Be sure to tie the cord of the special tool to the
1nearby part.
2. Loose the nut but do not remove it.
IO. DISCONNECTION OF TIE ROD END
Using the special tool, disconnect the tie rod end from the
knuckle.
Caution1. Be sure to tie the cord of the special tool to the
nearby part.
2. Loose the nut but do not remove it.

FRONT DISC BRAKE PAD CHECK AND REPLACE-
MENiNWFOAF
NOTE
The brake pads have wear indicators that contact the brake discd’when the brake pad thickness becomes 2 mm
(.08 in.), and
emit a squealing sound to warn the driver.
1. Check brake pad thickness through caliper body check
port.Limit: 2.0 mm
(.08 in.)
Caution1. When the limit is exceeded, replace the pads at
both sides, and also the brake pads for the wheelson the opposite side at the same time.
2.If there is a significant difference in the thicknesses
of the pads on the left and right sides, check the
sliding condition of the piston, lock pin sleeve and
guide pin sleeve.
2.Remove lock or guide pin. Lift caliper assembly and retain
with wires.
Caution
Do not wipe off the special grease that is on the guide
-pin or allow it to contaminate the guide pin.
3. Remove the following parts from caliper support.

14A0407FRONT BRAKE DISC RUN-OUT
CORRECTIO&wAB
1.If the run-out of the brake disc is equivalent to or exceeds 5the limit specification, change the phase of the disc and
-’hub, and then measure the run-out again.
(1) Before removing the brake disc, chalk both sides of the
wheel stud on the side at which run-out is greatest.
(2) Remove the brake disc, and then place a dial gauge as
shown in the illustration; then move the hub in the axialdirection and measure the play.
Limit: 0.008 mm
(00031 in.)
If the play is equivalent to or exceeds the limit,
disassemble the hub knuckle and check each part.
(3) If the play does not exceed the limit specification, and
then check the run-out of the brake disc once again.
Mount the brake disc on the position dislocated from
the chalk mark.

2.If the run-out cannot be corrected by changing the phase-ofI’the brake disc, replace the disc.

2.If there is a significant difference in the thicknesses
of the pads on the left and right sides, check the
