If the run-out of the brake disc is equivalent to or exceeds
the limit specification, change the phase of the disc and
hub, and then measure the run-out again.
(1) Before removing the brake disc, chalk both sides of the
wheel stud on the side at which run-out is greatest.
(2) Remove the brake disc, and then place a dial gauge as
shown in the illustration; then move the hub in the axial
direction and measure the play.
Limit: 0.2 mm (.008 in.)
If the play is equivalent to or exceeds the limit, disas-
semble the hub knuckle and check each part.
(3) If the play does not exceed the limit specification, and
then check the run-out of the brake disc once again.
Mount the brake disc on the position dislocated from
the chalk mark.
If the run-out cannot be corrected by changing the phase
of the brake disc, replace the disc or turn rotor with on the
car type brake lathe (MAD DL-8700PF or equivalent).
Using a micrometer, measure disc thickness at eight posi-
tions, approximately 45" apart and 10 mm (.39 in.) in from
the outer edge of the disc.
Brake Disc Thickness
Standard value: 24 mm (.94 in.)
Limit: 22.4 mm (.882 in.)
Thickness Variation (At least 8 position)
The difference between any thickness
ments should not be more than 0.015 mm (.OOOS
in.).
If the disc is beyond the limits for thickness,
install a new one. If thickness variation exceeds the specifi-
cation, replace the disc or turn rotor with on the car type
brake lathe (MAD, DL-8700PF or equivalent).
