INSPECTION AND REPAIR
1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness:
12.0 mm (0.472 in.)
Minimum thickness:
1.0 mm (0.039 in.)
Replace the pads if the thickness is less than the minimum
(the 1.0 mm slit is no longer visible) or if it shows signs of un-
even wear.
2. MEASURE DISC THICKNESS
Using a micrometer, measure the disc thickness.
Standard thickness:
30.0 mm (1.181 in.)
Minimum thickness:
28.0 mm (1.102 in.)
Replace the disc if the thickness of the disc is at the minimum
thickness or less. Replace the disc or grind it on a lathe if it
is badly scored or worn unevenly.
3. MEASURE DISC RUNOUT
Using a dial indicator, measure disc runout 10 mm (0.39 in.)
from the outer edge of the disc.
Maximum disc runout:
0.05 mm (0.0020 in.)
If the disc's runout is at the maximum value or greater, check
the bearing play in the axial direction and check the axle hub
runout (See page SA±16). If the bearing play and axle hub
runout are not abnormal, adjust the disc runout.
4. IF NECESSARY, ADJUST DISC RUNOUT
(a) Remove the hub nuts and the disc. Reinstall the disc 1/5 of
a turn round from its original position on the hub. Install and
torque the hub nuts.
Torque: 103 NVm (1,050 kgfVcm, 76 ftVlbf)
Remeasure the disc runout. Make a note of the runout and
the disc's position on the hub.
(b) Repeat (a) until the disc has been installed on the 3
remaining hub positions.
(c) If the minimum runout recorded in (a) and (b) is less than 0.05
mm (0.0020 in.), install the disc in that position.
(d) If the minimum runout recorded in (a) and (b) is greater than
0.05 mm (0.0020 in.), replace the disc and repeat step 3.
HINT: Install a disc marked with ºRº on the right wheel, and
a disc marked with ºLº on the left wheel.
