1. MEASURE PAD LINING THICKNESS Standard thickness: 10.5 mm (0.413 in.) Minimum thickness: 3.0 mm (0.118 in.)
Replace the pad if the thickness is less than the minimum (the 1.0 mm slit is no longer visible) or if it shows sign of uneven wear.
2. MEASURE ROTOR DISC THICKNESS
Standard thickness: 18.0 mm (0.709 in.) Minimum thickness: 17.0 mm (0.669 in.)
If the disc thickness is less than minimum, replace the disc.
3. MEASURE ROTOR DISC RUNOUT
(a) Temporarily install the hub nuts in reverse.
(b) Measure the rotor disc runout at 10 mm (0.39 in.) from the outer edge of rotor disc.
If the runout is greater than the maximum, replace the disc.
4. IF NECESSARY, REPLACE ROTOR DISC
(a) Remove the torque plate from the rear axle housing.
(b) Remove the rotor disc and hub nuts.
(c) Install the rotor disc, and adjust the shoe clearance.
(d) Install the torque plate onto the rear axle housing. Torque: 475 kg-cm (34 ft-lb. 47 Nm)
