REAR BRAKE INSPECTION

  1. INSPECT BRAKE CYLINDER AND PISTON

    1. Check the cylinder bore and piston for rust and scoring. If necessary, replace the rear disc brake cylinder assembly and/or piston.

  2. INSPECT PAD LINING THICKNESS

    1. Using a ruler, measure the pad lining thickness.

      *1 Ruler
      Standard thickness
      10.5 mm (0.413 in.)
      Minimum thickness
      1.0 mm (0.0394 in.)

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

      Tech Tips

      Be sure to check the wear of the rear disc when replacing the brake pads.

  3. INSPECT REAR DISC BRAKE PAD SUPPORT PLATE

    1. Make sure that the rear disc brake pad support plates have sufficient rebound, no deformation, cracks or wear, and that all rust and dirt are removed.

      If necessary, replace the rear disc brake pad support plates.

  4. INSPECT DISC THICKNESS

    1. Using a micrometer, measure the disc thickness.

      *1 Micrometer
      Standard thickness
      10.0 mm (0.394 in.)
      Minimum thickness
      8.5 mm (0.335 in.)

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

  5. INSPECT DISC RUNOUT

    1. Inspect the rear axle hub bearing looseness and axle hub runout Click here.

    2. While holding the disc using SST, tighten the disc with the 5 hub nuts.

      SST
      09330-00021
      A011VW1E01
      Torque:
      103 N*m  { 1049 kgf*cm, 76 ft.*lbf }

    3. Using a dial indicator with magnetic base, measure the disc runout 10 mm (0.394 in.) away from the outer edge of the rear disc.

      *1 Dial Indicator
      Maximum disc runout
      0.15 mm (0.00591 in.)

      Note

      Keep the magnet of the dial indicator away from the rear axle hub and bearing assembly.

      If the runout exceeds the maximum value, change the installation position of the disc to minimize the runout. If the runout exceeds the maximum even when the installation position is changed, grind the disc. If the disc thickness is less than the minimum, replace the rear disc.

    4. Remove the 5 nuts and rear disc.
