RUN-OUT CHECK
1.
Remove the caliper support; then raise the caliper ass
upward and secure by using wire.
2.
Inspect the disc surface for grooves, cracks, and rust. Cl
the disc throughly and remove all rust.
3. Place a dial gauge approximately 5 mm
in.) from
outer circumference of the brake disc, and measure
run-out of the disc.
Limit: 0.07 mm
in.)
NOTE
Tighten the nuts in order to secure the disc to the hub..
RUN-OUT CORRECTION
1.
If the run-out of the brake disc is equivalent to or exceeds
the limit specification, change the phase of
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
shown in the illustration; then move the hub in the axial
direction and measure the play.
Limit: 0.2 mm
in.)
If the play is equivalent to or exceeds the limit, disas-
semble the hub knuckle and check each part.
2.
(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
or equivalent).’
