WARNING
It is important to completely understand the operation of your bicycle's brake system.
Improper use of your bicycle's brake system may result in a loss of control or an accident, which could lead to severe injury. Because each bicycle may handle differently, be sure to learn the proper braking technique (including brake lever pressure and bicycle control characteristics) and operation of your bicycle. This can be done by consulting your professional bicycle dealer and the bicycle's owners manual, and by practicing your riding and braking technique.
Securely tighten the caliper brake mounting nuts to the specified tightening torque.
Use lock nuts with nylon inserts (self-locking
nuts) for nut-type brakes.
For sunken nut type brakes, use sunken nuts of
the appropriate length which can be turned six
times or more; when re-installing, apply sealant
(locking adhesive) to the nut threads.
If the nuts become loose and the brakes fall off, they may get caught up in the bicycle and the bicycle may fall over. Particularly if this happens with the front wheel, the bicycle may be thrown forward and serious injury could result.
Obtain, read and carefully service instructions when installing parts. A loose, worn, or damaged parts may cause injury to the rider.
We strongly recommend that only genuine
Shimano replacement parts be used.
