2. Measure the thickness of brake disc;
Standard thickness20.0mm
Min thickness18.0mm
If the brake pad is scraped, repair it; where the abrasion is
serious and its thickness is smaller than the min thickness,
change the brake disc.
3. Measure the bounding value of the brake disc face;
Remark: the bearing is required to be verified in the suitable
adjustment before measuring.
Max face bouncing value: 0.11mm;
4. Change the brake disc according to the requirement:
(a) Tear down the hub and the brake disc. (see the paragraph
of front wheel hub)
(b) Mount the new brake disc and screw up the connecting
bolts as the specified torque.
(c) Mount the hub and brake disc assembly. (see the para-
graph of front wheel hub).
Fastening torque(755)Nm
(d) Mount the caliper bracket on the steering knuckle and
screw up the bolts according to the specified torque.
Fastening torque123Nm.
