.
3.
If runout is outside the limit, find the minimum runout point by
shifting the mounting positions of disc rotor and wheel hub by
one hole.
Thickness Inspection
1.
Using a micrometer, check thickness of disc rotor. If thickness is
outside the standard, replace disc rotor.
2.
If runout is still out of the specification, grind rotor with on-car
brake lathe (

CALIPER INSPECTION
Cylinder Body
CAUTION:
• Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.
• Check inner wall of cylinder for corrosion, wear, and damage. If any non-standard condition is
detected, replace cylinder body.
• Minor flaws caused by corrosion or a foreign material can be removed by polishing the surface with
a fine sandpaper. Replace the cylinder body, if necessary.
Torque Member
Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.

Apply brake fluid or rubber grease to the piston boot, place it on
the piston, and firmly insert the piston boot cylinder-side lip into
the cylinder body groove.
CAUTION:
Do not reuse the piston boot.
3.
Apply a brake fluid to the piston, insert into the cylinder body by
hand and firmly attach the piston boot piston-side lip into the pis-
ton boot.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
