UNTIL 2. Check the rotor while assembled to the hub or spoke wheel
SEATED
and mounted on the axle spindle. The lateral runout of the
rotor friction material surfaces should not exceed 0.015-inch
(0.381 mm) total indicator reading (TIR). The thickness
variation of the rotor should not exceed 0.0012-inch
(0.0300 mm).

If the lateral runout or the thickness variation exceeds
the above values: Resurface or replace the rotor.
Caliper
1. Inspect the caliper before reinstalling it onto the torque plate.
The pistons should be fully retracted into the caliper. Check
to ensure the piston boots are not loose or damaged. Verify
the piston boots are fully seated into the housing. If any
leakage, damage or defect is found, it may be necessary to
disassemble or replace the caliper. Figure 6.7.
