In the manufacturing process of the brake rotor:
| • | Tolerances of the braking surfaces are checked for flatness |
| • | Thickness variation is observed |
| • | Lateral runout is closely maintained |
| | The maintenance of close tolerances on the shape of the braking surfaces
is necessary to prevent brake roughness or pulsation. |
| • | In addition to these tolerances the surface finish must be maintained
to a specified texture. The control of the braking surface finish is necessary
to avoid the following braking concerns: |
| • | Light scoring of the rotor surfaces not exceeding 1.5 mm
(0.060 in) in depth is not detrimental to brake operation and may
result from normal use. |
