Important safety information
WARNING
Because each bicycle may handle slightly differently depending on the
model, be sure to learn the proper braking technique (including brake
lever pressure and bicycle control characteristics) and operation of your
bicycle. Improper use of your bicycle's brake system may result in a loss
of control or a fall, which could lead to severe injury.
Do not disassemble or modify the product. This may cause the product
to not operate correctly, and you may suddenly fall and be seriously
injured.
Do not apply the front brake too strongly. If you do so, the front wheel
may lock and the bicycle may fall forward, and serious injury may result.
Because the required braking distance will be longer during wet
weather, reduce your speed and apply the brakes early and gently. You
may fall or collide and be seriously injured.
A wet road surface may cause tires to lose traction; therefore, to avoid
this, reduce your speed and apply the brakes early and gently. If the
tires lose traction, you may fall and be seriously injured.
Do not allow any oil or grease to get onto the brake shoes. Riding the
bicycle with oil or grease on the brake shoes may prevent the brakes
from operating and result in serious injury due to a fall or collision.
Do not use the brake cable if it has any rust, fraying, or cracks.
Otherwise, the brakes may not work correctly.
Please use extra caution to keep your fingers away
from the rotating disc brake rotor. The disc brake
rotor is sharp enough to inflict severe injury to your
fingers if caught within the openings of moving
rotor.
Do not touch the calipers or disc brake rotor while riding or
immediately after dismounting from the bicycle. The calipers and disc
brake rotor will become hot when the brakes are operated, so you may
get burned if you touch them.
Do not allow any oil or grease to get onto the disc brake rotor and
brake pads. Riding the bicycle with oil or grease on the disc brake rotor
and brake pads may prevent the brakes from operating and result in
serious injury due to a fall or collision.
Check the thickness of the brake pads and do not use them if they have
a thickness of 0.5 mm or less. Doing so may prevent the brakes from
operating and result in serious injury.
2 mm 0.5 mm
Do not use the disc brake rotor if it is cracked or deformed. The disc
brake rotor may break, and result in serious injury due to a fall. Replace
the disc brake rotor with a new one.
Do not use the disc brake rotor if its thickness is 1.5 mm or less. Also do
not use it if the aluminum surface becomes visible. The disc brake rotor
may break, and result in serious injury due to a fall. Replace the disc
brake rotor with a new one.
CAUTION
Disc brakes have a bed-in period, and the braking force will gradually
increase as the bed-in period progresses. Accidents or falls may occur
due to losing control of the bicycle, possibly resulting in serious injury.
(The same thing will happen when the brake pads or disc brake rotor
are replaced.)
Notice
Also, read carefully all manuals included with the brake caliper.
Products are not guaranteed against natural wear and deterioration
from normal use and aging.
For maximum performance we highly recommend Shimano lubricants
and maintenance products.
Regular inspections before riding the bicycle
Before riding the bicycle, check the following items. If any problems are
found, consult your place of purchase or a distributor.
Do the front and rear brakes work correctly?
Is the gap in the brake lever sufficient?
Does the brake cable have any rust, fraying, or cracks?
Have the brake shoes worn down to the grooves?
Do the brake pads have a thickness of 0.5 mm or more?
Are there signs of cracks or peeling on the levers?
Are there any abnormal noises?
