PROCEDURE
INSPECT BRAKE CYLINDER AND PISTON
Check the rear disc brake cylinder bore and rear disc brake piston for rust and scoring. If necessary, replace the rear disc brake cylinder assembly and rear disc brake piston.
INSPECT PAD LINING THICKNESS
| *a | Ruler |
Using a ruler, measure the rear disc brake pad lining thickness.
| Standard Thickness |
|---|
| 12.0 mm (0.472 in.) |
| Minimum Thickness |
|---|
| 1.0 mm (0.0394 in.) |
If a rear disc brake pad lining thickness is less than the minimum thickness, replace the rear disc brake pads.
Tech Tips
Be sure to check rear disc thickness when replacing the rear disc brake pads with new ones.
INSPECT REAR DISC BRAKE PAD SUPPORT PLATE
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 cleaned off. If necessary, replace the rear disc brake pad support plates.
INSPECT DISC THICKNESS
| *a | Micrometer |
Using a micrometer, measure the rear disc thickness.
| Type | Minimum Thickness | Standard Thickness |
|---|---|---|
| for Solid Disc | 8.5 mm (0.335 in.) | 10.0 mm (0.394 in.) |
| for Ventilated Disc | 16.5 mm (0.650 in.) | 18.0 mm (0.709 in.) |
If the rear disc thickness is less than the minimum thickness, replace the rear disc.
INSPECT DISC RUNOUT
Inspect the rear axle hub bearing looseness and rear axle hub runout.
Using SST to hold the rear disc, tighten the rear disc with the 5 hub nuts.
| *a | Dial Indicator |
Using a dial indicator, measure the disc runout 10 mm (0.394 in.) from the outer edge of the rear disc.
| Maximum Disc Runout |
|---|
| 0.05 mm (0.00196 in.) |
Note
Keep the magnet of the dial indicator away from the rear axle hub and bearing assembly and rear speed sensor.
If the runout exceeds the maximum value, change the installation position of the rear disc to minimize the runout. If the runout exceeds the maximum even when the installation position is changed, replace the rear disc.
Remove the 5 hub nuts and rear disc.
