INSPECTION

1.

MEASURE PAD LINING THICKNESS

Using a ruler, measure the pad lining thickness.

Standard thickness: 10.0 mm (0.39 in.)
Minimum thickness: 1.0 mm (0.039 in.)

Replace the pad if the pad’s thickness is at the minimum or if
it shows signs of uneven wear.
2.

MEASURE DISC THICKNESS

(a)

Temporarily fasten the disc with the 3 hub nuts.

(b)

Using a micrometer, measure the disc thickness.
Standard thickness: 18.0 mm (0.709 in.)
Minimum thickness: 16.0 mm (0.611 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
scored or is worn unevenly.

3.

MEASURE DISC RUNOUT

Using a dial indicator, measure the disc runout at a position 10
mm (0.39 in.) from the outside edge.

Maximum disc runout: 0.1 mm (0.0039 in.)

If the disc’s runout is at the maximum value or greater, check the
bearing play is in the axial direction and check the axle hub run-
out (See page 

SA–95

). If the bearing play and axle hub runout

are not abnormal, adjust the disc runout or grind it on an ”On–
Car” brake lathe.
4.

IF NECESSARY, ADJUST DISC RUNOUT

(a)

Remove the 2 bolts and torque plate from the backing
plate.

(b)

Remove the hub nuts and the disc. Reinstall the disc ro-
tating 1/6 of a turn from its original position on the hub.
Install and torque the hub nuts.
Torque: 110 N·m (1,122 kgf·cm, 81 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 4 re-
maining hub positions.

(d)

If the minimum runout recorded in (b) and (c) is less than
0.1 mm (0.0039 in.), install the disc in that position.

(e)

If the minimum runout recorded in (b) and (c) is greater
than 0.1 mm (0.0039 in.), replace the disc and repeat step
3.

(f)

Install the torque plate and tighten the 2 bolts.
Torque: 105 N·m (1,070 kgf·cm, 77 ft·lbf)
