INSPECTION
1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness: 11.5 mm (0.453 inch)
Minimum thickness: 1.0 mm (0.039 inch)
Replace the pad if the thickness is less than the minimum (the 1.0 mm slit is no longer visible), or if it shows signs of uneven wear.
2. MEASURE DISC THICKNESS
Using a micrometer, measure the disc thickness.
Standard thickness: 28.0 mm (1.102 inch)
Minimum thickness: 26.0 mm (1.024 inch)
Replace the disc if the thickness of the disc is at the minimum or less. Replace the disc or grind it on a lathe if it is scored or worn unevenly.
3. MEASURE DISC RUNOUT
Using a dial indicator, measure the disc runout at a position 10 mm (0.39 inch) from the outside edge.
Maximum disc runout: 0.07 mm (0.0028 inch)
If the runout is greater than the maximum, replace the disc or grind it on a "On-Car" brake lathe.
