BRAKE: REAR DISC BRAKE:

INSPECTION

1. INSPECT BRAKE CYLINDER AND PISTON
(a) Check the cylinder bore and piston for rust or scoring.
2. INSPECT PAD LINING THICKNESS





(a) Using a ruler, measure the pad lining thickness.
Standard thickness:
10.0 mm (0.394 in.)
Minimum thickness:
1.0 mm (0.039 in.)
3. INSPECT DISC THICKNESS





(a) Using a micrometer, measure the disc thickness.
Standard thickness:
9.0 mm (0.354 in.)
Minimum thickness:
7.5 mm (0.295 in.)
4. INSPECT DISC RUNOUT
(a) Temporarily fasten the disc with hub nuts.
Torque: 103 Nm (1,050 kgf-cm, 76 ft-lbf)





(b) Using a dial indicator, measure the disc runout 10 mm (0.39 in.) away from the outer edge of the disc.
Maximum disc runout:
0.15 mm (0.0059 in.)
(c) If the disc runout is the maximum value or greater, check the bearing play in the axial direction and check the axle hub runout (Rear Axle Hub). If the bearing play and axle hub runout are normal, adjust the disc runout or grind it on a "On-car" brake lathe.
