Standard thickness: 12.5 mm (0.492 in.)
Minimum thickness: 2.0 mm (0.079 in.)
(b)Inspect the 2 front disc brake pad support plates No.2 and front disc brake pad support plates No.1.
Make sure that they have sufficient rebound, no deforma-
tion, cracks nor wear, and have had all rust, dirt and for-
eign particles cleaned off.
14.INSPECT DISC THICKNESS
(a)Using a micrometer, measure the front disc thickness.
Standard thickness: 26.0 mm (1.024 in.)
Minimum thickness: 24.0 mm (0.945 in.)
15.REMOVE FRONT DISC
(a)Place matchmarks on the front disc and the axle hub.
(b)Remove the front disc.

(b)Using a dial indicator, measure the front disc runout 10 mm (0.39 in.) away from the outer edge of the front disc.
Maximum disc runout: 0.05 mm (0.0020 in.)
(c)If the disc's runout is maximum value or greater, check the
bearing play in the axial direction and check for the axle
hub runout (See page 30±2). If the bearing play and axle
hub runout are normal, adjust the disc runout or grind it
on a ºOn±carº brake lathe.
