6. Measure the hub torque before and after pad installation.
Follow the procedure:
Front: Refer to
Rear: Refer to
CAUTION
Do not apply excessive grease. Excessive grease may
cause brake performance to become poor.
7. For front disc brake <2.4L ENGINE> and rear disc bake
<3.0L ENGINE>, apply brake grease SAE J310, NLGI
number 1 to the following positions before installing the pad.
<FRONT (2.4L ENGINE)>
•
Pad and wear indicator assembly and inner shim A contact
surface
•
Inner shim A and inner shim B contact surface
•
Pad assembly and outer shim A contact surface
•
Outer shim A and inner shim B contact surface
<REAR (3.0L ENGINE)>
•
Pad and wear indicator assembly and inner shim A contact
surface
•

DISC BRAKE ROTOR CHECK
M1351002900066
CAUTION
Disc brakes must be kept within the allowable
service values in order to maintain normal brake
operation.
Before turning the brake disc, the following
conditions should be checked.
FRONT DISC BRAKE RUN-OUT CHECK AND
CORRECTION
M1351009400084
1. Remove the caliper support; then raise the caliper assembly
upward and secure it with a wire.
2. Inspect the disc surface for grooves, cracks and rust. Clean
the disc thoroughly and remove all rust.
INSPECTION ITEMS
REMARKS
Scratches, rust, saturated lining materials and wear
•
If the vehicle is not driven for a long period of
time, sections of the discs that are not in contact
with the pads will become rusty, causing noise
and shuddering.
•
If grooves and scratches resulting from excessive
disc wear are not removed prior to installing a
new pad assembly, there will be inadequate con-
tact between the disc and the lining (pad) until the
pads conform to the disc.
Run-out
Excessive run-out of the discs will increase the pedal
depression resistance due to piston kick-back.
Change in thickness (parallelism)
If the thickness of the disc changes, this will cause
pedal pulsation, shuddering and surging.
Warping (flatness) or distortion
Overheating and improper handling while servicing
will cause warping or distortion.

3. Place a dial gauge approximately 5 mm (0.2 inch) from the
outer circumference of the brake disc, and measure the run-
out of the disc.
Limit: 0.06 mm (0.002 inch)
4. If the run-out of the brake disc is limit value or more, turn
rotor with an on-car type brake lathe ("Accuturn-8750" or
equivalent). If it still exceeds the limit, inspect hub end play.
Limit: 0.05 mm (0.002 inch)
5. If the play exceeds the limit, check the hub. If the play does
not exceed the limit, replace the brake disc.
REAR DISC BRAKE RUN-OUT CHECK AND
CORRECTION
M1351009400103
1. Remove the caliper support; then raise the caliper assembly
upward and secure it with a wire.
2. Check the disc surface for grooves, cracks and rust. Clean
the disc thoroughly and remove all rust.
3. Place a dial gauge approximately 5 mm (0.2 inch) from the
outer circumference of the brake disc, and measure the run-
out of the disc.
Limit: 0.08 mm (0.003 inch)
4. If the run-out of the brake disc is the limit value or more,
change the phase of the disc and hub, and then measure
the run-out again.
(1) Before removing the brake disc, place a mating mark on
both the wheel stud and disc with chalk where the run-out
is greatest.

(2) Place a dial gauge as shown in the illustration, and then
move the hub in the axial direction and measure the play.
Limit: 0.05 mm (0.002 inch)
(3) If the play does not exceed the limit install the brake disc
at a different phase, and then check the run-out of the
brake disc again.
5. If the run-out cannot be corrected by changing the phase of
the brake disc, replace the disc.
BRAKE DISC THICKNESS CHECK
M1351002400050
<Front>
1. Remove dirt and rust from the brake disc surface.
2. Using a micrometer, measure disc thickness at eight
positions, approximately 45 degrees apart and 10 mm (0.4
inch) in from the outer edge of the disc.
2.4L ENGINE
Standard value: 24.0 mm (0.9 inch)
Minimum limit: 22.4 mm (0.88 inch)
3.0L ENGINE
Standard value: 26.0 mm (1.02 inch)
Minimum limit: 24.4 mm (0.96 inch)
NOTE: Thickness variation (at least 8 positions) should not be
more than 0.015 mm (0.0006 inch).
3. If the disc thickness is less than the limits, replace it with a
new one. If thickness variation exceeds the specification,
turn rotor with an on-the-car type brake lathe ("Accuturn-
8750" or equivalent).
If the calculated final thickness after turning the rotor is less
than the standard value, replace the disc.
