WARNING

Brake operation 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.

Front brakes Brakes designed for use as rear brakes should not
be used as front brakes.

Shimano parts Obtain and read the service instructions carefully
prior to installing the parts. Loose, worn, or damaged parts may
cause serious injury to the rider. We strongly recommend only
using genuine Shimano replacement parts.

Shimano BR-M960 Safety Information

WARNING

The M960 brake system is equipped with an adjustment block in
the wire hooking unit of the ST-M960 brake lever which allows
the rider to change the relationship between the brake input and
output. If the adjustment block is removed, the braking force will
be dramatically increased, so that a high level of braking
performance can be achieved from only a small amount of lever
movement. Accordingly, normal braking operation may cause a
greater-than-expected amount of braking force to be applied,
which could make the bicycle fall forward, causing serious injury
to the rider. To avoid this, please read the following instructions
thoroughly before removing the adjustment block.

After removing the adjustment block, make sure that
you are completely used to the new braking
characteristics before riding the bicycle, otherwise the
bicycle might fall forward if you have to apply the
brakes suddenly, such as when a vehicle appears.

1)

Without adjustment block removed (standard
specifications for shipment)

– To avoid serious injuries:

With adjustment block

2)

With adjustment block removed

An ample degree of braking force can be obtained from a
small amount of brake lever input, to provide a high level of
brake performance. However, if the brakes are operated
suddenly, there is the danger that the bicycle may fall forward.
After removing the adjustment block, first ride the bicycle at a
speed of less than 6 mph (10 km/h) while applying the brakes
repeatedly in order to get a feel for the difference in braking
characteristics before riding at higher speeds. Beginners
should be particularly careful.

No adjustment block

Use the BR-M960 V-Brake with SERVO WAVE ACTION
and adjustable V-Brake-compatible levers such as the
ST-M960 /ST-M952 / BL-M950 brake levers.

NOTE:

By using these parts as a set, the optimum efficiency of the Multi­Condition Brake System can be realized.

Parts such as the brake shoes are not guaranteed against wear
of deterioration in the quality of their materials.

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.
