PROCEDURE
INSPECT BRAKE CYLINDER AND PISTON
Check the rear disc brake cylinder assembly 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
Using a ruler, measure the rear disc brake pad lining thickness.
| Standard Thickness |
|---|
| 13.5 mm (0.531 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 the rear disc thickness when replacing the rear disc brake pads with new ones.
INSPECT REAR DISC BRAKE ANTI-RATTLE SPRING
Clean the No. 1 anti-rattle spring, inner anti-rattle spring and check it for deformation and cracks.
When installing the No. 1 anti-rattle spring to the rear disc brake cylinder, check that the spring's force is applied to the hole pin and rear disc brake pad.
INSPECT DISC THICKNESS
| *a | Micrometer |
Using a micrometer, measure the rear disc thickness.
| Standard Thickness |
|---|
| 25.0 mm (0.984 in.) |
| Minimum Thickness |
|---|
| 23.0 mm (0.906 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.
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 |
|---|
| 0.04 mm (0.00157 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.
