1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness:
1 ton: 9.5 mm (0.374 in.)
Standard thickness:
0.5 ton: 11.0 mm (0.433 in.)
Minimum thickness:
1.0 mm (0.039 in.)
BR0251
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: 25.0 mm (0.984 in.)
Minimum thickness: 23.0 mm (0.906 in.)
Replace the disc if the thickness of the disc is at the minimum
thickness or less. Replace the disc or grind it on a lathe if it is
scored or is worn unevenly.

3. MEASURE DISC RUNOUT
Using a dial indicator, measure the disc runout 10 mm (0.39 in.)
from the outside edge of the disc.
Maximum disc runout: 0.07 mm (0.0028 in.)
If the runout is greater than the maximum, replace the disc or
grind it on a "On−Car" brake lathe.

Before measuring the runout, check that the front hub bearing
play is within specification.
