CAUTION

• After a new brake disc is installed, always

grind the brake disc with on-the-car type
brake lathe. If this step is not carried out, the
brake disc run-out exceeds the specified
value, resulting in judder.

•

When the on-the-car type lathe is used, first

install M12 flat washer on the stud bolt in the
brake disc side according to the figure, and
then install the adapter. If the adapter is
installed with M12 flat washer not seated, the
brake disc rotor may be deformed, resulting
in inaccurate grinding.

• Grind the brake disc with all wheel nuts

diagonally and equally tightened to the
specified torque 100 N

⋅m. When all numbers

of wheel nuts are not used, or the tightening
torque is excessive or not equal, the brake
disc rotor or drum may be deformed,
resulting in judder.

2. 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 ("MAD, DL-8700PF" or equivalent). If
the calculated final thickness after turning the
rotor is less than the standard value, replace the
disc.

BRAKE DISC RUN-OUT CHECK AND
CORRECTION

CAUTION

The vehicle speed detection magnetic encoder
collects any metallic particle easily, because it is
magnetised. When replacing brake disc, make
sure that the magnetic encoder does not collect
any metallic particle.
1. Remove the brake caliper assembly, and then

hold it with wire.

2. Temporarily install the disc with the hub nut.

3. Place a dial gauge approximately 5 mm from the

outer circumference of the brake disc, and
measure the run-out of the disc.

Limit:
<Front> 0.03 mm
<Rear> 0.04 mm

4. If the brake disc run-out exceeds the limit, correct

it as follows:
(1) Chalk phase marks on the wheel stud and the

brake disc, which run-out is excessive as
shown.

(2) Remove the brake disc. Then place a dial

gauge as shown, and measure the wheel
bearing axial play by pushing and pulling the
wheel hub.

Limit: 0.05 mm

(3) If the axial play exceeds the limit, replace the

wheel hub.

(4) If the axial play does not exceed the limit,

dephase the brake disc and secure it. Then
recheck the brake disc run-out.

CAUTION

• After a new brake disc is installed, always

grind the brake disc with on-the-car type
brake lathe. If this step is not carried out, the
brake disc run-out exceeds the specified
value, resulting in judder.

⋅m. When all numbers

of wheel nuts are not used, or the tightening
torque is excessive or not equal, the brake
disc rotor or drum may be deformed,
resulting in judder.

5. If the run-out cannot be corrected by changing the

phase of the brake disc, replace the brake disc or
grind it with the on-the-car type brake lathe
("MAD, DL-8700PF" or equivalent).
