Measure the brake disc thickness at several points.
Service limits:
- Front: 3.5 mm (0.14 in)
- Rear: 6.0 mm (0.24 in)
Replace the brake disc if the smallest measurement is less than service limit.
First make sure the wheel bearings are normal, or you will not get accurate results.
Check the brake disc for warpage.
Service limit: 0.30 mm (0.012 in).
Replace the brake disc if the warpage exceeds the service limit.
