INSPECTION

1.

MEASURE PAD LINING THICKNESS
(See step 1 on page

BR–29

)

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

)

Standard thickness: 10.0 mm (0.394 in.)
Minimum thickness: 9.0 mm (0.354 in.)

3.

MEASURE DISC RUNOUT
(See step 3 on page

)

Maximum disc runout: 0.15 mm (0.0059 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

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

4.

IF NECESSARY, ADJUST DISC RUNOUT

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.

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.
