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

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

   Standard thickness:

   10.0 mm (0.394 in.)
   

   Minimum thickness:

   1.0 mm (0.0394 in.)
   

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

   HINT:

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

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

1. Using a micrometer, measure the disc thickness.

   Standard thickness:

   25.0 mm (0.984 in.)
   

   Minimum thickness:

   22.0 mm (0.866 in.)
   

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

1. Inspect the front axle hub bearing looseness and front axle hub runout (Click here).
   

2. Using SST to hold the disc, tighten the disc with the 5 nuts.

3. 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.)
   

   NOTICE:

   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 front disc.
   

4. Remove the 5 nuts and front disc.
