PROCEDURE
INSPECT FRONT DISC BRAKE ANTI-RATTLE SPRING
Make sure that the front disc brake anti-rattle spring has sufficient rebound, no deformation, cracks or wear, and that all rust and dirt is cleaned off. If necessary, replace the front disc brake anti-rattle spring.
INSPECT PAD LINING THICKNESS
| *a | Ruler |
Using a ruler, measure the front disc brake pad lining thickness.
| Standard Thickness |
|---|
| 9.75 mm (0.384 in.) |
| Minimum Thickness |
|---|
| 1.0 mm (0.0394 in.) |
If a front disc brake pad lining thickness is less than the minimum thickness, replace the front disc brake pads.
Tech Tips
Be sure to check the front disc thickness when replacing the front disc brake pads with new ones.
INSPECT DISC
Check the surface of the front disc.
If the result of inspection is either of the following, replace the front disc.
The length of a crack is 46 mm (1.81 in.) or more. (A)
A crack reaches the outer or inner edge of the front disc. (B)
INSPECT DISC THICKNESS
| *a | Micrometer |
Using a micrometer, measure the front disc thickness.
| Standard Thickness |
|---|
| 34.0 mm (1.339 in.) |
| Minimum Thickness |
|---|
| 31.0 mm (1.220 in.) |
If the front disc thickness is less than the minimum thickness, replace the front disc.
INSPECT DISC RUNOUT
Inspect the front axle hub bearing looseness and front axle hub runout.
Using SST to hold the front disc, tighten the front disc with the 5 hub nuts.
| *a | Dial Indicator |
Using a dial indicator, measure the disc runout 7 mm (0.276 in.) from the outer edge of the front disc.
| Maximum Disc Runout |
|---|
| 0.05 mm (0.00196 in.) |
Note
Keep the magnet of the dial indicator away from the front axle hub sub-assembly and front speed sensor.
If the runout exceeds the maximum value, change the installation position of the front disc to minimize the runout. If the runout exceeds the maximum even when the installation position is changed, replace the front disc.
Remove the 5 hub nuts and front disc.
