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

WARNING:
Clean dust on caliper and brake pad with a vacuum du st collector to minimize the hazard of airborne
particles or other materials.
CAUTION:
 While removing cylinder body, never depr ess brake pedal because piston will pop out.
 It is not necessary to remove bolts on torq ue member and brake hose except for disassembly or
replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch
brake hose.
 Do not damage piston boot.
 If any shim is subject to serious corrosion, replace it with a new one.
 Always replace shims and shim covers as a set when replacing brake pads.
 Keep rotor clean, from brake fluid.
 Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or if a soft
pedal occurs at very low mileage. Refer to BR-29, "
Brake Burnishing Procedure".

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.
