runout of the disc.
Brake disc runoutLimit:
0.04 mm (0.0016 in.) or less (new one)
|

|
2. |
If the runout of the brake disc
exceeds the limit specification, replace the disc, and then measure the
runout again. |
3. |
If the runout does not exceed
the limit specification, install the brake disc after turning it 180° and
then check the runout of the brake disc again. |
