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
