General Safety Information
WARNING
• Please use extra caution to keep your fingers away from the rotating
disc brake rotor during installing or servicing the wheel. The rotor is
sharp enough to inflict severe injury to your fingers if caught within the
openings of moving rotor.
• 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 mm or
more.
• 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 pressure and bicycle
control characteristics) and 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.
• The M545 disc brakes are designed for optimum performance when used in combination
with the BR-M545 (calipers), ST-M410 (brake lever), SM-RT61, SM-RT62 (rotor) and
Shimano pad unit (M06). The brake lever used should be a two-finger lever for V-brakes,
such as the ST-M410.
If using in combination with 4-finger levers such as the BL-T400/ST-T400, the braking
force will be higher. Accordingly, under some conditions such as certain riding positions
or overall weight, the bicycle may fall over and injury may result if proper care is not
taken.
• Obtain and read the service instructions carefully prior to installing the parts. Loose,
worn, or damaged parts may cause injury to the rider.
We strongly recommend only using genuine Shimano replacement parts.
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.
CAUTION
• 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.
Note
• If the brake caliper mounting boss and the dropout are not parallel, the rotor and caliper
may touch.
• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
• For maximum performance we highly recommend Shimano lubricants and maintenance
products.

While wearing gloves, apply a force to the
rotor to turn it in a clockwise direction as
shown in Fig. 2. While doing this, tighten
the rotor fixing bolts in the order shown in
the illustration.
Use a flat-tipped screwdriver or similar tool to bend the edges of the tightening
plate over the heads of the bolts as shown in Fig. 3.
