INSPECTION1. 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: 11.0 mm (0.433 in.)
Minimum thickness: 1.0 mm (0.039 in.)
3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE
(a) Make sure that they have sufficient rebound, no deformation, cracks or wear, and have had all rust and dirt cleaned off.
4. INSPECT DISC THICKNESS
(a) Using a micrometer, measure the disc thickness.
Standard thickness: 25.0 mm (0.984 in.)
Minimum thickness: 23.0 mm (0.906 in.)
5. INSPECT DISC RUNOUT
(a) Temporarily fasten the disc with hub nuts.
Torque: 103 N*m (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: 0.05 mm (0.0020 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.
If the bearing play and axle hub runout are normal, adjust the disc runout or grind it on a "On-car" brake lathe.
