INSPECTION AND REPAIR OF FRONT BRAKE COMPONENTS 1. MEASURE PAD LINING THICKNESS Standard thickness: 10.0 mm (0.394 in.) Minimum thickness: 1.0 mm (0.039 in.) Replace the pad if the thickness is less than the minimum or if it shows sing of uneven wear. 2. MEASURE ROTOR DISC THICKNESS Standard thickness: 22.0 mm (0.866 in.) Minimum thickness: 21.0 mm (0.827 in.) If the disc is scored or worn, or if thickness is less than minimum, repair or replace the disc. 3. MEASURE ROTOR DISC RUNOUT HINT: Before measuring the runout, confirm that the front hub bearing play is within specification. Measure the rotor disc runout at 10 mm (0.39 in.) from the outer edge of the rotor disc. Maximum disc runout: 0.13 mm (0.0051 in.) If the runout is greater than the maximum, inspect and ad- just it following the procedure below: Then replace the disc if necessary. (a) Remove the torque plate from the knuckle. (b) Remove the hub nuts of the temporarily installed disc and pull off the rotor disc. (c) Check that the hub axial play is within specification, and replace the bearing if not within specification. (See page FA-8) (d) Install the rotor disc and hub nuts on the axle hub shaft the rotor disc one fifth of a turn and measure the runout. Similarly measure the runout at each po- sition, and select the position where the runout is minimum. (e) In this position, if the runout is within specification, install the torque plate and torque the mounting bolts. Torque: 1,065 kg-cm (77 ft-lb, 104 N-m) (f) If not within specification, replace the rotor disc, and repeat (d) and (e).
