1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness: 11.5 mm (0.453 in.)
Minimum thickness: 1.0 mm (0.039 in.)
Replace the pad if the pad's thickness is at the minimum thick-
ness or less, or if the pad has severe, uneven wear.

2. MEASURE DISC THICKNESS
Using a micrometer, measure the disc thickness.
Standard thickness: 25.0 mm (0.984 in.)
Minimum thickness: 23.0 mm (0.906 in.)
Replace the disc if the disc's thickness is at the minimum thick-
ness 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 the disc runout 10 mm (0.39 in.)
away from the outer edge of the disc.
Maximum disc runout: 0.05 mm (0.0020 in.)
If the disc's runout is maximum value or greater, check the bear-
ing play in the axial direction and check the axle hub runout
(See page SA−13). If the bearing play and axle hub runout are
not abnormal, adjust the disc runout or grind it on a "On−car"
brake lathe.

4. IF NECESSARY, ADJUST DISC RUNOUT
(a) Remove the 2 bolts and torque plate from the knuckle.
(b) Remove the hub nuts and the disc. Reinstall the disc in
the position turned 1/5 from its original position on the
hub. Install and torque the hub nuts.
Torque: 103 N·m (1,050 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-
R09267
maining hub positions.
(d) If the minimum runout recorded in (b) and (c) is less than
0.05 mm (0.0020 in.), install the disc in that position.
(e) If the minimum runout recorded in (b) and (c) is greater
than 0.05 mm (0.0020 in.), replace the disc and repeat
step 3.
(f) Install the torque plate and torque the mounting bolts.
Torque: 107 N·m (1,090 kgf·cm, 79 ft·lbf)
