Shimano BR-7700 Caliper Brake Service Instructions | Manualzz

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 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.

NOTE

If using SHIMANO's road brake shoes in combination with ceramic rims, the brake shoes will wear more quickly than normal.

The thickness of the BR-7700 brake shoe has been increased by

1 mm from the previous thickness. If the width of the tire is greater than 23 mm, the tire may interfere with the shoes and cause an obstruction when installing and removing the wheel, even when the quick release lever is in the open position.

When these brake shoes are installed with the BR-6500/BR-5500/

BR-5501 brakes, they may cause an obstruction when installing and removing the wheel if the tire width is greater than 26 mm.

For maximum performance we highly recommend Shimano lubricants and maintenance products.
