REAR BRAKE INSPECTION


  1. CHECK PAD LINING THICKNESS


    1. A01DOZ1

      Using a ruler, measure the pad lining thickness.

      Standard thickness
      10.0 mm (0.394 in.)
      Minimum thickness
      1.0 mm (0.0394 in.)

      If the pad lining thickness is less than the minimum, replace the pad.

      Tech Tips

      Be sure to check the wear on the rear disc after replacing the brake pad with a new one.

  2. CHECK DISC THICKNESS


    1. A01DS58

      Using a micrometer, measure the disc thickness.

      Standard thickness
      18.0 mm (0.709 in.)
      Minimum thickness
      16.0 mm (0.630 in.)

      If the disc thickness is less than the minimum, replace the disc.

  3. CHECK DISC RUNOUT


    1. A01DQCD

      Install the disc with the 6 hub nuts.

      Torque:
      112 N*m  { 1137 kgf*cm, 82 ft.*lbf }

    2. Using a dial indicator, measure the disc runout at a position 10 mm (0.394 in.) from the outside edge.

      Maximum disc runout
      0.20 mm (0.00787 in.)

      If the disc runout is more than the maximum, check the rear axle shaft Click here. If the rear axle shaft is normal, adjust the disc runout or grind the disc using an on-vehicle brake lathe.

  4. ADJUST DISC RUNOUT


    1. Remove the 2 bolts and rear disc brake cylinder mounting from the backing plate.

    2. Remove the hub nuts and disc. Rotate the disc 1/5 of a turn from its original position on the hub and install the disc with the hub nuts.

      Torque:
      112 N*m  { 1137 kgf*cm, 82 ft.*lbf }

    3. Measure the disc runout. Make a note of the runout and the disc position on the hub.

    4. Repeat the 2 previous steps until the disc has been installed on the 3 remaining hub positions. If the minimum runout recorded above is less than 0.20 mm (0.00787 in.), install the disc in that position. If the minimum runout recorded above is more than 0.20 mm (0.00787 in.), replace the disc and repeat the "Check Disc Runout" procedure.
