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: 0.03 mm or less
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.
(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: 0.06 mm <Front>, 0.05 mm <Rear>
(3) If the wheel bearing axial play exceeds the limit,
disassemble the hub and knuckle assembly to check
each part.
(4) If the wheel bearing axial play does not exceed the
limit, dephase the brake disc and secure it. Then
recheck the brake disc run-out.
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).
Caution
(1) 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.
(2) 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.
(3) 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.

INSTALLATION
Tighten the brake booster mounting nuts (A), and then the
brake pedal mounting bolts (B).
NOTE
The pedal support member can not be positioned correctly
if the pedal mounting bolts (B) are tightened first as the their
holes are oblong holes.

1. Connect an ohmmeter between the stop lamp switch
connector terminals.
2. There should be no continuity between the terminals when
the plunger is pushed in as shown. There should be
continuity when it is released.
