General Safety Information
WARNING
• Adjust the inner cable so that
the protruding length is less
than 20 mm (3/4 inch). If the
protruding length is any
longer, the end of the inner
cable may become stuck in the
rotor, which could cause the
wheel to lock and the bicycle
could fall forward causing
serious injuries.
• The calipers and rotor will become hot when
the brakes are operated, so do not touch them
while riding or immediately after dismounting
from the bicycle, otherwise you may get
burned. Check that the brake components have
cooled down sufficiently before attempting to
adjust the brakes.
• Always make sure that the front and rear
brakes are working correctly before you ride
the bicycle.
• Before riding the bicycle, check
that the pad thicknesses are
0.5 (0.9) mm or more.
• If noise occurs when the brakes
are operated, it may indicate
that the brake pads have worn
down to their usage limit. After
checking that the brake system
has cooled down sufficiently,
check the brake pad thicknesses.
Replace the brake pads if the pad
wear indicators are visible.
• Be careful not to allow any oil or
grease to get onto the rotor and brake pads,
otherwise the brakes may not work correctly.
• If any oil or grease do get on the pads, you
should replace the pads. If any oil or grease
gets on the rotor, you should clean the rotor.
If this is not done, the brakes may not work
correctly.
• Check the brake cable for rust and fraying, and
replace the cable immediately if any such
problems are found. If this is not done, the
brakes may not work correctly.
• The required braking distance will be longer
during wet weather.
Reduce your speed and apply the brakes early
and gently.
• If the road surface is wet, the tires will skid
more easily. If the tires skid, you may fall off
the bicycle. To avoid this, reduce your speed
and apply the brakes early and gently.
• Check that the quick release lever is on the
right side (the opposite side to the rotor). If the
quick release lever is on the same side as the
rotor, there is the danger that it may interfere
with the rotor, so check that it does not
interfere.
• It is important to completely understand the
operation of your bicycle's brake system.
Improper use of your bicycle's brake system may
result in a loss of control or an accident, which
could lead to severe injury. Because each bicycle
may handle differently, be sure to learn the
proper braking technique (including brake lever

operation of your bicycle. This can be done by
consulting your professional bicycle dealer and
the bicycle's owners manual, and by practicing
your riding and braking technique.
• Obtain, read and carefully service instructions
when installing parts. A loose, worn, or
damaged parts may cause injury to the rider.
We strongly recommend that only genuine
Shimano replacement parts be used.
• Read these Technical Service Instructions
carefully, and keep them in a safe place for
later reference.

• Disc brakes have a burn-in period, and the
braking force will gradually increase as the
burn-in period progresses. Make sure that you
are aware of any such increases in braking force

when using the brakes during the burn-in
period. The same thing will happen when the
brake pads or rotor are replaced.
