C: INSPECTION
1) Check the front wheel bearing play and axle hub
runout before the inspection of disc rotor runout
limit.
2) Secure the disc rotor by tightening the five wheel
nuts.
3) Set a dial gauge 10 mm (0. 39 in) inward from
the disc rotor outer circumference. Rotate the disc
rotor to check runout. If the disc rotor runout ex-
ceeds the limit, replace with a new disc rotor. After
grinding, check disk rotor thickness according to
step 4).
Disc rotor runout limit:
0.05 mm (0.0020 in)
4) Set a micrometer 10 mm (0.39 in) inward from

NOTE:
•Always replace the pads on both sides as a set.
•Replace pad clips if they are twisted or worn.
•A wear indicator is installed on the inner disc
brake pad. If the pad is worn to the limit, the end of
wear indicator contacts disc rotor, and a squeaking
sound is heard as the wheel rotates. If the sound is
heard, replace the pad.
•Replace the pad if there is oil or grease on it.

screwdriver until the brake shoe moves ade-
quately away from the disc rotor.
(2) If it is difficult to remove the disc rotor from
the hub, drive an 8 mm bolt into the threads B of
the rotor, then remove the rotor.
