INSPECTION
1. MEASURE PAD LINING THICKNESS (See page
BR-31)
Standard thickness: 10.0 mm (0.394 in.)
Minimum thickness: 1.0 mm (0.039 in.)
2. MEASURE DISC THICKNESS
(See step 2 on page BR-31)
Standard thickness: 12.0 mm (0.472 in.)
Minimum thickness: 10.5 mm (0.413 in.)
3. MEASURE DISC RUNOUT
(See step 3 on page BR-31)
Maximum disc runout: 0.15 mm (0.0059 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-45). If the bearing play and axle hub runout are
not abnormal, adjusting the disc runout or grind it on a ºOn-Carº
brake lathe.
4. IF NECESSARY, ADJUST DISC RUNOUT
(a) Remove the 2 bolts and torque plate.
(b) 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 N´m (1050 kgf´cm, 76 ft´lbf)
Remeasure the disc runout. Make a note of the runout
and the disc's position on the hub.
(c) Repeat (b) until the disc has been installed on the 3 re-
maining hub positions.
(d) If the minimum runout recorded in (b) and (c) is less than
0.15 mm (0.0059 in.), install the disc in that position.
(e) If the minimum runout recorded in (b) and (c) is greater
than 0.15 mm (0.0059 in.), replace the disc and repeat
step 3.
(f) Install the torque plate and torque the mounting bolts.
