User manual SHIMANO BR-7900 MOUNTING

[. . . ] · Use lock nuts with nylon inserts (self-locking nuts) for nuttype 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. [. . . ] · 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.
