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 assembly and front disc brake piston.

2. INSPECT PAD LINING THICKNESS

   1. 

      Using a ruler, measure the pad lining thickness.

      Standard Thickness

      Item	Specified Condition
      Inner Pad	11.5 mm (0.453 in.)
      Outer pad	12.0 mm (0.472 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.

      Tip:

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

4. INSPECT DISC THICKNESS

   1. 

      Using a micrometer, measure the disc thickness.

      Standard thickness

      26.0 mm (1.02 in.)

      Minimum thickness

      23.0 mm (0.906 in.)

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

5. INSPECT DISC RUNOUT

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

   2. Install the disc with the 5 hub nuts.

   3. 

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

      Maximum runout

      0.05 mm (0.00197 in.)

      If the runout is more than the maximum, change the installation position of the disc to minimize runout. If the runout is more than 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.
