REAR BRAKE (for Disc Type) INSPECTION

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.

INSPECT PAD LINING THICKNESS

   *1

   Ruler

   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 equal to the minimum thickness or less, replace the brake pads with a disc brake pad kit.

   Tech Tips

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

INSPECT REAR DISC BRAKE PAD SUPPORT PLATE

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

INSPECT DISC THICKNESS

*1	Micrometer

1. Using a micrometer, measure the disc thickness.

   Standard thickness
   9.0 mm (0.354 in.)

   Minimum thickness
   7.5 mm (0.295 in.)

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

INSPECT DISC RUNOUT

1. Inspect the rear axle hub bearing looseness and axle hub runout Click here.

2. Tighten the disc with the 4 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 rear disc.

   Maximum disc runout
   0.15 mm (0.00591 in.)

   Note

   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 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 rear disc.

4. Remove the 4 nuts and rear disc.
