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.
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 serious
injury to the rider. 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.
Installation of the brake lever
Use a 5 mm Allen key to install the brake lever.
In order to realize the best performance, we recommend that the
following combination be used.
Installation of the V-BRAKE brake
While holding the shoe against the rim, adjust the amount of
shoe protrusion by changing over the washer B (thick or
thin) so that dimension A is kept at 32 mm or more.
General Safety Information
Shimano BR-MX70 Safety Information
The BR-MX70 V-BRAKE brake can only be used as a rear brake.
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.
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.
