General Safety Information
WARNING
– To avoid serious injuries:
• Improper use of your bicycle's brake system may result in a loss of control
or an accident, which could lead to a severe injury. Because each bicycle
may handle differently, be sure to learn the proper braking technique
(including brake lever pressure and bicycle control characteristics) for your
bicycle. Consult your bicycle dealer and the bicycle's owners manual, and
practice your riding and braking technique.
• If the front brake is applied too strongly, the wheel may lock and the
bicycle may fall forward, and serious injury may result.
• Brakes designed for use as rear brakes should not be used as front
brakes.
• Obtain and read the service instructions carefully prior to installing the
parts. Loose, worn or damaged parts may cause the bicycle to fall over
and serious injury may occur as a result. We strongly recommend only
using genuine Shimano replacement parts.
• Be careful not to allow any oil or grease to get onto the brake shoes. If
any oil or grease do get on the shoes, you should replace the shoes,
otherwise 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.
• Always make sure that the front and rear brakes are working correctly
before you ride the bicycle.
• 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.
• Read these Technical Service Instructions carefully, and keep them in a
safe place for later reference.
Note
• The optimum efficiency of the Multi-Condition Brake System can be
realized by using the brakes and brake levers in the recommended set.
• If the brake shoes have worn down until the grooves are no longer visible,
they should be replaced.
• Different brake shoes have their own characteristics. Ask the place of
purchase for details when purchasing the brake shoes.
• Parts are not guaranteed against natural wear or deterioration resulting
from normal use.
• For maximum performance we highly recommend Shimano lubricants and
maintenance products.
• For any questions regarding methods of handling or maintenance, please
contact the place of purchase.

Brake System
Multi-Condition Brake System
By providing superior wet weather braking performance (control and
modulation), braking performance will not vary in a multitude of conditions
when using this brake system.
In order to realize the best performance, we recommend that the
following combination be used.

Installation of the brake lever
Use a 5 mm Allen key to install the brake lever.

Tightening torque:
6 – 8 N·m {52 – 69 in. lbs.}
When installing the
components to carbon
frame/handle bar surfaces,
verify with the manufacturer
of the carbon frame/parts for
their recommendation on
tightening torque in order to prevent over tightening that can
cause damage to the carbon material and/or under tightening
that can cause lack of fixing strength for the components.
Installation of the cantilever brake
1.
Insert the stopper pin of the brake body into the center spring
hole in the frame mounting boss, and then secure the brake
body to the frame with the link fixing bolt.

There are two different types of shoe and shoe holder to be
used in the left and right positions respectively. Slide the new
shoes into the grooves on the shoe holders while taking note
of the correct directions and pin hole positions.
If the cable carrier is in the position in the illustration, then
setting is complete. Check to be sure that there is a clearance
of 20 mm or more between the outer casing holder and the
cable carrier as shown in the illustration for step 8. This is to
ensure that the cable carrier does not touch the outer casing
holder. If it does touch, the brakes will not work.
