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


    1. A01CFTRE01

      Using a ruler, measure the pad lining thickness.

      Standard thickness of a new pad
      12.0 mm (0.472 in.)
      Minimum thickness
      1.0 mm (0.0394 in.)

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

      Tech Tips

      Be sure to check the wear of the front disc after replacing the brake pads with new ones.

  3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE


    1. Make sure that the disc brake pad support has sufficient rebound, no deformation, cracks or wear, and that all rust and dirt are cleaned off. If necessary, replace the disc brake pad support plate.

  4. INSPECT DISC THICKNESS


    1. A01CGIJ

      Using a micrometer, measure the disc thickness.

      Standard thickness of a new disc
      28.0 mm (1.10 in.)
      Minimum thickness
      25.0 mm (0.984 in.)

      Tech Tips

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

  5. INSPECT DISC RUNOUT


    1. Tighten the disc with the 5 nuts.

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

    2. Inspect the front axle hub bearing looseness and front axle hub runout Click here.

    3. A01CC9A

      Using a dial indicator, measure the disc runout 10 mm (0.394 in.) away from the outer edge of the front disc.

      Maximum disc runout
      0.05 mm (0.00197 in.)

      If the runout exceeds the maximum, change the installation position of the disc to minimize 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 front disc.

      Note

      Keep the magnetic parts of the dial indicator away from the front axle hub and speed sensor.

    4. Remove the 5 nuts and front disc.
