2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that wheel bearing axle end
play is within the sp ecification. Refer to FA X - 4 , "
On-Vehicle
Inspection" (2WD models), FA X - 11 , "On-Vehicle Inspection"
(AWD models).
3. If runout is outside the limit, find the minimum runout point by shifting the mounting positions of disc rotor and wheel hub by one hole.
4. If runout is still outside the limit after performing the above operation, replace or lathe the disc rotor.
[When lathing, use the Pro-Cut PFM On-Car Br ake Lathe (Tool No, 38-PFM90.5) or equivalent.]
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
Brake Burnishing ProcedureINFOID:0000000001327632
Burnish brake pad contact surfaces of disc rotor according to following procedure after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:
 Be careful of vehicle speed because brake does no t operate easily until pad and disc rotor are
securely fitted.
 Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicl e within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted. Measurement point
: At a point 10.0 mm (0.394 in)
from outer edge of disc.
Runout limit : 0.04 mm (0.0016 in) or less

3. Apply brake fluid to piston, and press piston into cylinder bodyby hand to assemble piston side lip on piston boot properly into
groove on piston.
CAUTION:
Press piston evenly and change the pressing point to pre-
vent the inner wall of cylinder from being rubbed.
4. Fix piston boot with retaining ring. CAUTION:
 Make sure boot is firmly in cylinder body groove.
 Do not reuse retaining ring.
5. Install sliding pin bolts and sliding pin boots to torque member.
6. Apply PBC (Poly Butyl Cuprysil) grease or silicone- based grease to the backside of brake pad and to both
sides of shim, and attach inner shim and shim cover to inner pad, and the outer shim to outer pad.
7. Assembling shims and shim cover to pad. CAUTION:
When attaching pad retainer, inst all it firmly so that it does
not float up higher than torque member, as shown in the fig-
ure.
8. Install brake pad retainer and pad to torque member.
9. Install cylinder body. Tighten sliding pin bolts to the specified torque. Refer to BR-24, "
Component".
10. After installing caliper assembly, refill with new brake fluid and bleed air. Refer to BR-8, "
Bleeding Brake System".
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cra cks, and serious damage. If a malfunction is detected,
replace applicable part.
Runout Inspection
1. Using wheel nuts, fix the disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that wheel bearing axle end
play is within the specification. Refer to RAX-6, "
On-Vehicle
Inspection".
3. If runout is outside the limit, find minimum runout point by shift- ing mounting positions of disc rotor and wheel hub by one hole.

WHEEL SENSORS
WHEEL SENSORS
Removal and InstallationINFOID:0000000001327698
REMOVAL
1. Disconnect wheel sensor connector.
2. Remove wheel sensor mounting bolts, grommets (front sensor) and clip.
3. Remove wheel sensor.
CAUTION:
Be careful of the followin
g when installing sensor.
 As much as possible, avoid rotati ng sensor when removing it. Pull sensors out without pulling on
sensor harness.
 Take care to avoid damaging sensor edges or roto r teeth. Remove wheel sensor first before remov-
ing front wheel hub and bearing assembly and rear fina l drive. This is to avoid damage to sensor wir-
ing and loss of sensor function.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful of the follow ing when installing sensor. Tighten in stallation bolts to specified torques.
 When installing, make sure there is no foreign material such as iron chips on pick-up and mounting
hole of sensor. Make sure no foreign material h as been caught in the sensor rotor. Remove any for-
eign material and clean the mount.
 When installing front sensor, be sure to press rubber grommets in until they lock at the three loca-
tions shown in the figure (2 at shock absorbers and 1 at body pa nel). When installed, harness must
not be twisted. White line on ha rness must be visible from front.
 When installing rear sensor, attach harness at rear suspension member securely. Besides, harness
must not be twisted when installed.
