3. If the runout is out of specification, find minimum runout posi-
tion as follows:
a.
Remove nuts and rotor from wheel hub.
b.
Shift the rotor one hole and secure rotor tho wheel hub
with nuts.
c.
Measure runout.
d.
Repeat steps a. to c. so minimum runout position can be
found.
4. If the runout is still out of specification, turn rotor with on-car
brake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or
equivalent).
