INSPECTION
1. CHECK BRAKE CALIPER AND PISTON
(a) Check the caliper bore and piston for rust or scoring.
If necessary, replace the disc brake caliper assembly.
2. CHECK PAD LINING THICKNESS
(a) Using a ruler, measure the pad lining thickness.
Standard thickness:
11.9 mm (0.469 in.)
Minimum thickness:
1.0 mm (0.0394 in.)
If the pad lining thickness is less than the minimum, replace the
pad.
HINT:
Be sure to check the wear on the front disc after replacing the
brake pad with a new one.
3. CHECK FRONT DISC BRAKE ANTI-RATTLE SPRING
(a) Use brake cleaner to clean the front disc brake anti-rattle spring. Check for deformation and cracks.
(b) When installing the front disc brake anti-rattle spring to the front disc brake caliper, check that the
spring's force is applied to the hole pin and brake pad.
4. CHECK DISC THICKNESS
(a) Using a micrometer, measure the disc thickness.
Standard thickness:
32.0 mm (1.26 in.)
Minimum thickness:
29.0 mm (1.14 in.)
If the disc thickness is less than the minimum, replace the disc.
5. CHECK DISC RUNOUT
(a) Tighten the disc with the 5 hub nuts.
Torque:
for Aluminum Wheel -
131 N·m {1336 kgf·cm, 97ft·lbf}
for Steel Wheel -
209 N·m {2131 kgf·cm, 154ft·lbf}

(b) Using a dial indicator, measure the disc runout 10 mm (0.394
0.05 mm (0.00197 in.)
If the runout is more than the maximum, change the installation
If the runout is more than the maximum even when the
installation positions are changed, check the bearing looseness
in the axial direction
and the axle hub runout
.
If the bearing looseness and the axle hub runout are normal, and
if the disc thickness is not within the specified range, grind the
disc.
If the disc thickness is less than the minimum, replace the disc.
(c) Remove the 5 hub nuts and front disc.
