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.

(3) With an AWD model, put the shift lever in
1st (MTT) or L(A/T) position, rotate the wheels and observe the wave
shape for each wheel. With an FWD model, put the shift
lever in
1st (M/T) or L (AiT) position, rotate the wheels and
observe the wave shape for the front wheels; for the rear
wheels, rotate the wheels by hand and monitor the wave
shape.

If it is too low, check each wheel speed sensor,
With FWD rear wheels, check the sensor gap.
IS THERE VARIATION IN THE WAVE SHAPE AMPLITUDE?
If the flicker of the amplitude is large, consider shaking

Care must be taken not to scratch or scar the rotor’stoothed surface, and not to drop it.
If the rotor’s toothed surface is chipped or the rotor is
deformed, it might not be able to accurately sense the

INSPECTION
SPEED SENSOR CHECK
(1) Check whether any metallic foreign material has adhered to
the pole piece at the speed sensor tip, and, is so, remove it.Also check whether the pole piece is damaged, and, if so,
hreplace it with a new one.

NOTEThe pole piece can become magnetized because of the
magnet built into the speed sensor, with the result that
metallic foreign material easily adheres to it. Moreover, the
pole piece may not be able to function to correctly sense
the wheel rotation speed if it is damaged.
(2) Measure the resistance between the speed sensor termi-
nals.Standard value:
0.8-1.2 kQIf. the internal resistance of the speed sensor is not within
the standard value, replace it with a new speed sensor.
(3) Check the speed sensor cable for breakage, damage or
disconnection; replace with a new one if a problem is
found.
NOTE
When checking for cable damage, remove the cable clamppart from the body and then bend and pull the cable near
the clamp to check whether or not temporary disconnec-
tion occurs.
TOOTHED ROTOR CHECKCheck whether rotor teeth are broken or deformed, and, if so,
replace the rotor.
SERVICE POINTS OF INSTALLATION
11. INSTALLATION OF REAR SPEED SENSOR BRACKET
Assemble the speed sensor and the speed sensor bracket.
NOTEThe shape is different for the left and right speed sensor
brackets. Each bracket has an identification symbol, so be
sure to note these symbols and install correctly.
R: Indicates that the bracket is for the right wheel.
L: Indicates that the bracket is for the left wheel.

10. INSTALLATION OF REAR SPEED SENSOR (1) Teimn;rarily install the speed sensor to the rear axle
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 metal
objects.(2) Note the following points when connecting the speed
sensor cable, and secure the cable by the clip.
@I Secure the clip so that the white-painted part
(shaded in the illustration) of the speed sensor cableis not twisted.
@ Be sure that there is space (where shown in the
illustration) so that the trailing arm and speed
sensor cable do not contact, and then secure by the
clip.
Caution
Because there is the possibility of damage to the
cable during driving if the speed sensor cable and
the trailing arm come into contact, or if the speed
sensor cable is twisted, care must be taken regard-
ing this point.(3) Insert a feeler gauge into the space between the speed
sensor’s pole piece and the rotor’s toothed surface, andthen tighten the speed sensors at the position where
the clearance is the standard value.
Standard value:
0.3-0.9 mm (.012-.035 in.)
NOTECheck to be sure that there is no contact of the speed
sensor’s pole piece and the rotor’s toothed surface
when the rear hub assembly is slowly rotated one time.
If there is contact, it is probable that the rotor or the rearhub is installed incorrectly, recheck installation.
