INSPECTION PROCEDURE 1. INSPECT BRAKE CYLINDER AND PISTON
(a)
Check the front disc brake cylinder bore and front disc brake piston
for rust and scoring. If necessary, replace the front disc brake
cylinder assembly and front disc brake piston. 2. INSPECT PAD LINING THICKNESS
| (a) Using a ruler, measure the front disc brake pad lining thickness.
Standard Thickness: 11.0 mm (0.433 in.) Minimum Thickness:
1.0 mm (0.0394 in.)
HINT:
- If a front disc brake pad lining thickness is less than the minimum thickness, replace the front disc brake pads.
- Be sure to check front disc thickness when replacing the front disc brake pads with new ones.

3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE (a)
Make sure that the front disc brake pad support plates have sufficient
rebound, no deformation, cracks or wear, and that all rust and dirt is
cleaned off. If necessary, replace the front disc brake pad support
plates. 4. INSPECT DISC THICKNESS
| (a) Using a micrometer, measure the front disc thickness. Standard Thickness:
28.0 mm (1.10 in.) Minimum Thickness: 25.0 mm (0.984 in.)
HINT: If the front disc thickness is less than the minimum thickness, replace the front disc. |
|
5. INSPECT DISC RUNOUT (a) Inspect the front axle hub bearing looseness and front axle hub runout.
Click here  (b) Temporarily install the front disc with the 5 hub nuts.
Torque: 103 N·m {1050 kgf·cm, 76 ft·lbf}
| (c) Using a dial indicator with magnetic base, measure the disc runout 10 mm (0.394 in.) from the outer edge of the front disc.
Maximum Disc Runout: 0.05 mm (0.00196 in.) NOTICE: Keep the magnet of the dial indicator away from the front speed sensor.
HINT: If
the runout exceeds the maximum value, change the installation position
of the front disc to minimize the runout. If the runout exceeds the
maximum even when the installation position is changed, grind the front
disc. If the front disc thickness is less than the minimum, replace the
front disc. |
