MEASURE PAD LINING THICKNESS Using a ruler, measure the pad lining thickness. Standard thickness: 11.0 mm (0.433 in.) Minimum thickness: 1.0 mm (0.039 in.) Replace the pad if the pad’s thickness is at the minimum thick- ness or less, or if the pad has severe and uneven wear. 2. MEASURE DISC THICKNESS Using a micrometer, measure the disc thickness. Standard thickness: 28.0 mm (1.102 in.) Minimum thickness: 26.0 mm (1.024 in.) Replace the disc if the disc’s thickness is at the minimum thick- ness or less. Replace the disc or grind it on a lathe if it is badly scored or worn unevenly. 3. MEASURE DISC RUNOUT Using a dial indicator, measure disc runout 10 mm (0.39 in.) away from the outer edge of the disc. Maximum disc runout: 0.05 mm (0.0020 in.) If the disc’s runout is the maximum value or greater, check the bering play in the axial direction and check the axle hub runout (See page SA–9 ). If the bearing play and axle hub runout are not abnormal, adjust the disc runout or grind it on a ”On–Car” brake lathe. 4. IF NECESSARY, ADJUST DISC RUNOUT (a) Remove the torque plate from the knuckle. (b) Remove the hub nuts and the disc. Reinstall the disc in the position turned 1/5 from its original position on the hub. Install and torque the hub nuts.
