1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness: 11.5 mm (0.453 in.) Minimum thickness: 1.0 mm (0.039 in.)
Replace the pad if the pad's thickness is at the minimum or if it shows signs of uneven wear.
2. MEASURE DISC THICKNESS
Using a micrometer, measure the disc thickness.
Standard thickness: 32.0 mm (1.260 in.) Minimum thickness: 30.0 mm (1.181 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 at a position 10 mm (0.39 in.) from the out side edge.
Maximum disc runout: 0.07 mm (0.0028 in.)
If the bearing play and axle hub runout are not abnormal, replace the disc or grind it on an "On-Car brake lathe".
HINT: Before measuring the runout, confirm that the front bearing preload is within the specification ( SA-16 ).
4. IF NECESSARY, REPLACE DISC
(a) Remove the front axle hub ( SA-12 ).
(b) Remove the disc from the axle hub (SA-13 ).
(c) Install a new disc and torque the 5 bolts.
Torque: 74 NÂ·m (750 kgfÂ·cm, 54 ftÂ·lbf)
(d) Install the axle hub and adjust the front bearing preload ( SA-16 ).
Installation is in the reverse order of removal ( BR-19 ).
Reassembly is in the reverse order of disassembly ( BR-20 ).
HINT: Apply lithium soap base glycol grease to the parts indicated by the arrows ( BR-18 ).
