To Inspect

(1) Inspect the machined faces of the disc for
scores, cracks, wear and signs of overheating. (2) Using a micrometer, measure the thickness
of the disc at several posit ions around the face of the
disc. Renew the disc if the minimum thickness is
below Specifications.

(3) If the disc thickness is satisfactory but the
disc is scored, machine equal amounts from the
machined face on each side of the disc, to restore the
serviceability of the disc.


Inspect the machined faces of the disc for scores,
cracks, wear and signs of overheating.
NOTE: Disc machining is best entrusted to
a reliable brake specialist who can advise on
disc serviceability.
