FRONT BRAKE INSPECTION


  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

    A0137VWE01

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

      Standard thickness
      11.0 mm (0.433 in.)
      Minimum thickness
      1.0 mm (0.039 in.)

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

  3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE


    1. Make sure that the front disc brake pad supports have sufficient rebound, that there is no deformation, cracks or wear, and that all rust and dirt are removed.

      If necessary, replace the disc brake pad support plate.

  4. INSPECT DISC THICKNESS

    A0136OVE01

    1. Using a micrometer, measure the disc thickness.

      Standard thickness
      20.0 mm (0.787 in.)
      Minimum thickness
      18.0 mm (0.709 in.)

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

  5. INSPECT DISC RUNOUT


    1. Check the bearing play in the axial direction and check for the axle hub runout Click here.

    2. A0137W4

      Provisionally fasten the front disc together with the hub bolts.

      Torque:
      103 N*m  { 1,050 kgf*cm, 76 ft.*lbf }

    3. Using a dial indicator, measure the disc runout 10 mm (0.39 in.) away from the outer edge of the front disc.

      Maximum disc runout
      0.05 mm (0.0020 in.)

      If the disc runout is the maximum value or greater, grind it on an on-car brake lathe.
