3. Check brake lining.
a. Visually check brake lining for flatness, and also check for excessive wear. If condition of lining cannot
be confirmed accurately only by visual inspection, a physical check will be used as necessary.
b. Measure the minimum brake lining thickness. When
the minimum thickness of brake lining is 2 mm or less,
replace the brake lining.
c. When replacing excessively worn brake linings (inner and outer), it is also necessary to replace linings
on the opposite side of vehicle as well as unchecked linings to maintain proper braking performance. If
it is unnecessary to replace brake linings, be sure to reinstall brake linings to the original positions.
4. Check brake disc.
a. Minor scratch or wear on brake disc surface is acceptable. If severe scratch or deformation exists, the
brake disc must be replaced.
b. Excessive wear of brake disc may cause poor contact between brake lining and surface of brake disc. If
protrusion on the disc is not removed before installing new brake lining, abnormal wear of brake disc
will be caused.
c. It is normal that the surface of brake disc is worn when replacing brake lining. If cracks or burned spots
exist, the brake disc must be replaced.
5. Check brake disc thickness.
a. Using a vernier caliper, measure the brake disc
thickness at the center of brake lining contact surface
as shown in the illustration.
Standard thickness: 25 mm
Minimum thickness: 23 mm
b. If it is less than the minimum thickness due to wear of brake disc, replace brake disc.
CAUTION
 DO NOT machine brake disc, because it may make the brake disc thickness less than the minimum
thickness.
