General Safety Information
WARNING
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.
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 prob- •
lems 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 bicyc- •
le. 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.
CAUTION
The power modulator is a device that makes it easier to control braking by increasing the cable
stroke at the brake lever within a certain constant range of braking force.
If the effective operating range of the power modulator will be exceeded, the lever stroke and the
brake will operate as a normal V-BRAKE brake (sensitive and powerful). In that case, the brakes
may operate more powerfully than intended and may cause the wheel to lock up. Therefore it is
essential that you fully understand and test the performance of the power modulator before use.
The power modulator is not equipped with a function to prevent the wheel from locking up.
Shimano BR-M770 Safety Information
WARNING – To avoid serious injuries:
The M770 brake system is equipped with an adjustment block in the wire hooking unit of the
BL-M770/ST-M770 brake levers 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.
Without adjustment block removed (standard specifications for shipment) 1.
With adjustment block removed 2.
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.
NOTE:
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.
