5.
Mount a dial test indicator (DII) to the inboard side of the vertical link using the caliper assembly lower bolt hole (Illustration 3).
6.
Position the DTI probe 5 mm in from outer edge of disc.
7.
Measure the disc run-out with one rotation of the disc.
^
If the measured run-out is less than 0.04 mm then go to step 20.
^
If the measured run-out is greater than 0.04 mm then go to step 8.
8.
Remove the wheel nuts from the wheel studs.
9.
Remove the disc from the drive flange, rotate clockwise through 1800, reposition on the drive flange and secure as previously.
10.
Position the DTI probe 5 mm in from outer edge of disc.
11.
Measure the disc run-out with one rotation of the disc.
^
If the measured run-out is equal to the first measurement taken in step 7, then go to step L2.
^
If the measured run-out is less than the first measurement taken in step 7, but still greater than 0.04 mm then go to step 30.
^
If the measured run-out is less than 0.04 mm then go to step 20.
12.
Remove the wheel nuts from the wheel studs.
13.
Remove the brake disc from the flange, rotate clockwise through 90°, reposition on the drive flange and secure as previously.
14.
Position DTI probe 5 mm in from the outer edge of the disc.
15.
Measure the disc run-out with one rotation of the disc.
^
If the measured run-out is equal to the second measurement taken in step 11, then go to step 30.
^
If the measured run-out is greater than the second measurement taken in step 11, then go to step 16.
^
If the measured run-out is less than the second measurement taken in step 11 but still greater than 0.04 mm then go to step 30.
