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".
Removal and Installation of Brake PadINFOID:0000000001327635
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove sliding pin bolt (one on top).
3. Suspend cylinder body with a wire, and remove pads, pad retainers, shim from torque member.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silic one-based grease to the backside of pad and to both sides
of shim, and install inner shim and shim cover to inner pad, and install the outer shim to outer pad.
2. Install pad retainer and mount pad assemblies to torque member.
3. Push piston in so that pad is firmly installed and mount cylinder body to torque member. CAUTION:
When replacing pads with new ones, press in piston until pads can be installed. In this case, care-
fully monitor brake fluid level in reservoir tank because brake fluid will return to master cylinder
reservoir tank.
4. Install sliding pin bolt (one on top) and tighten to the specified torque. Refer to BR-24, "
Component".
5. Check brake for drag.
6. Install tires to the vehicle.

PRECAUTIONS
 If the following components are replaced with non-genui
ne components or converted, VDC OFF indicator
lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorber, strut, spring, bushing, etc.), Tires, wheels (exclude specified size),
components related to brake (pad, rotor, caliper, etc. ), components related to engine (muffler, ECM, etc.),
components related to body reinforcement (roll bar, tower bar, etc.).
 Driving in the condition of breakage or excessive wear of suspension, tires or components related to the
brakes may cause VDC OFF indicator lamp and SLIP indicator lamp turn on, and the VDC system may not
operate properly.
 When the TCS or VDC is activated by sudden accele ration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.
 When driving on roads which have extreme slopes (s uch as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate nor mally, or VDC OFF indicator lamp and SLIP indi-
cator lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after restart-
ing engine.
 Sudden turns (such as spin turns, acceleration turns) , drifting, etc. When VDC function is OFF (VDC OFF
SW ON) may cause the G sensor system indicate a malf unction. However, this is not a malfunction, if nor-
mal operation can be resumed after restarting engine.
 Change 4 tires at a time. Be sure to use specified- size tires that have the same brand name and pattern.
Wheel sensor errors can be detected be self-diagnosis when tires have wide abrasion variations or the size
is different from the genuine tires.

4. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
5. Turn ignition switch OFF, then turn it ON again. CAUTION:
Be sure to perform above operation.
6. Run vehicle with front wheels in straight-ahead position, then stop.
7. Select “DATA MONITOR”, “SELECTION FROM ME NU”, and “STR ANGLE SIG” on CONSULT-III screen.
Then make sure “STR ANGLE SIG” is within 0 ± 3.5 deg. If value is more than specification, repeat steps
1 to 6.
8. Erase memory of ABS actuator and electric unit (control unit) and ECM.
9. Turn ignition switch OFF.
Calibration of Decel G Sensor (AWD Models)INFOID:0000000001327659
NOTE:
After removing/installing or replacing yaw rate/side/dec el G sensor, ABS actuator and electric unit (control
unit), suspension components, or after adjusting wheel ali gnment, make sure to calibration of decel G sensor
before running vehicle.
CAUTION:
To calibrate decel G sensor, make sure to use CONS ULT-III. (Adjustment can not be done without CON-
SULT-III.)
1. Stop vehicle with front wheels in straight-ahead position.
CAUTION:
 The work should be done at a horizontal place when vehicle is in the unloaded vehicle condition.
 Keep all tires inflated to correct pressures. Ad just the tire pressure to the specified pressure
value.
2. Touch “WORK SUPPORT” and “DECEL G-SEN CALI BRATION” on CONSULT-III screen in this order.
3. Touch “START”. CAUTION:
Set vehicle as shown in the display.
4. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
