4. Hang cylinder body with a wire, and remove pads, pad retainers,shims, and shim covers from torque member.
CAUTION:
When removing the pad retainer from the torque member,
lift it in the direction indi cated by the arrow as shown so
that it does not deform.
INSTALLATION
1. Push piston in using suitable tool.
CAUTION:
In the case of replacing a pad with new one, ch eck the brake fluid level in the reservoir tank
because brake fluid returns to reservoir tank when pressing piston in.
NOTE:
Use a suitable tool to easily press piston.
2. Apply Molykote AS-880N grease or equivalent to between shim cover and shim. Install inner shim, inner shim cover to inner pad, and install outer shim, outer shim cover to outer pad.
3. Install pad retainers and pads to torque member. CAUTION:
• Securely assemble pad retainers so that they ar e not being lifted up from torque member.
• Both inner and outer pads have a pad return system on the pad retainer. Install pad return lever
securely to pad wear sensor.
4. Install cylinder body to torque member.
5. Install sliding pin bolts, and tighten it to the specified torque. Refer to BR-29, "
Removal and Installation of
Brake Pads".
6. Check front disc brake for drag and correct as necessary.
7. Install front wheel and tires. Refer to WT-41, "
Adjustment".
8. Check brake fluid level. Refer to BR-17, "
On Board Inspection".
Brake Burnishing ProcedureINFOID:0000000005856029
Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or
replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
• Be careful of vehicle speed because the brake does not operate easily until pad and disc rotor are securely seated.
• 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 vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool the brake.
4. Repeat steps 1 through 3 until pad and disc rotor are securely seated.

< SYMPTOM DIAGNOSIS >[WITH INTELLIGENT KEY SYSTEM]
SQUEAK AND RATTLE TROUBLE DIAGNOSES
Most of these incidents can be repaired by adjusting, se
curing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area c an often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the \
vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
