REAR BRAKE INSPECTION

PROCEDURE


  1. INSPECT BRAKE CYLINDER AND PISTON


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

  2. INSPECT PAD LINING THICKNESS

      *1 Ruler

      Using a ruler, measure the pad lining thickness.

      Standard thickness
      9.5 mm (0.374 in.)
      Minimum thickness
      1.0 mm (0.0394 in.)

      If the pad lining thickness is equal to the minimum thickness or less, replace the brake pads with a disc brake pad kit.

      Tech Tips

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

  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 Micrometer

      Using a micrometer, measure the disc thickness.

      Disc Thickness
      Disc Diameter Standard Thickness Minimum Thickness
      259 mm (10.2 in.) 9.0 mm (0.354 in.) 7.5 mm (0.295 in.)
      279 mm (11.0 in.) 10 mm (0.394 in.) 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.

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

      SST
      09330-00021
      Torque:
      103 N*m  { 1050 kgf*cm, 76 ft.*lbf }

      *1 Dial Indicator

      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.

      Maximum disc runout
      0.15 mm (0.00591 in.)

      Note

      Keep the magnet of the dial indicator away from the axle hub and speed sensor.

      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.
