FRONT 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

      Ruler

      Using a ruler, measure the pad lining thickness.

      Standard thickness
      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 thickness, replace the disc brake pad kit.

3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE

   
   

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

      If necessary, replace the disc brake pad support plate.

4. INSPECT DISC THICKNESS

      *1	Micrometer

      Using a micrometer, measure the disc thickness.

      Standard thickness
      22.0 mm (0.866 in.)

      Minimum thickness
      19.0 mm (0.748 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. Tighten the disc with the 5 nuts.

      Torque:

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

      *1	Dial Indicator

      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 value, change the installation positions of the disc and axle to make the minimum runout. If the runout exceeds the maximum even when the installation positions are changed, grind the disc. If the disc thickness is less than the minimum, replace the front disc.

   4. Remove the 5 nuts and front disc.
