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 ridi ng and bra king techniq ue.

•The BL-4600/BL-R780 brake levers are equipped with a mode switching
mechanism to make them compatible with V-BRAKE brakes, caliper brakes,
cantilever brakes and roller brakes.

If the incorrect mode is selected it may cause either excessive or
insufficient braking force to occur, which could result in dangerous
accidents. Be sure to select the mode in accordance with the
instructions given in the mode switching table.

•If the front brake is applied too strongly, the wheel may lock and the bicycle
may fall forward, and serious injury may result.

•Use the ST-4600/4603, BL-4600/R780 with the BR-4600.Do not use the BR­4600 in combination with previous STI levers for road riding or with the BL­R770/BL-R550 brake levers for flat handlebars, otherwise the braking
performance provided will be much too strong.

•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.

• 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 the bicycle to fall over and
serious injury may occur as a result. 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 bicycl e.

•The required braking distance will be longer during wet weather.Reduce
your spee d and apply the brakes early an d 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 the Service Instructions for the Brake Systems carefully before use.

•Read these Technical Service Instructions carefully, and keep them in a safe
place for later reference.

Note

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

•If the brake shoes have worn down until the grooves are no longer visible,
they should be replaced.

•Different brake shoes have their own characteristics.Ask the place of
purchase for details when purchasing the brake shoes.

•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.

– To avoid serious injuries:

When installing the components to carbon frame/handle bar
surfaces, verify with the manufacturer of the carbon frame/parts
for the ir reco mmendati on on t ightenin g torqu e in or der to
prevent over tightening that can cause damage to the carbon
material and/or under tightening that can cause lack of fixing
strength for the components.

Note:

The BR-4600 allows the angle of contact between the shoe
and the rim (toe-in) to be adjusted. Adjusting the toe-in
makes it possible to obtain smoother braking operation.

Note:

Cut the cable at the length at which it is not pulled tight
when the handlebar is turned all the way to the left and
right.

6. Check

Depress the brake lever about 10 times as far as the grip and
check that everything is operating correctly and that the shoe
clearance is correct before using the brakes.

3. Cable connection

Set the quick release lever to the closed position; then adjust
the shoe clearance (as shown in the illustration below) and
secure the cable.

•To increase the lever
stroke

Remove the pad spacer (A)
and install the bump rubber.

•To decrease the lever
stroke

Insert pad spacer (B) as far as
it will go and so that the
projections fit into the holes in
pad spacer (A).

* Apply a small amount of grease to the projections when installing

the pad spacer and the bump rubber.

4. Centering of the brake shoe

Make a minor adjustment by using the centering adjustment
screw.

Depress about

WARNUNG

Die Bremshebel sind mit einer
Betriebsartumschaltung ausgerüstet, um sie
kompatibel zu V-BRAKE-Bremsen,
Seitenzugbremsen, Mittenzugbremsen und
Klemmrollenbremsen zu machen. Die Einstellung der
falschen Betriebsart kann zu einem sehr scharfen
oder zu einem zu schwachen Ansprechverhalten der
Bremsen führen, was gefährliche Unfälle
verursachen kann. Wählen Sie deshalb die richtige
Betriebsart, entsprechend den Anweisungen in der
Tabelle Betriebsartumschaltung.

Lesen Sie die Bedienungsanleitung vor der
Verwendung der Bremse sorgfältig.

This brake lever is equipped with a mode switching

either excessive or insufficient braking force to occur,
which could result in dangerous accidents.
Be sure to select the mode in accordance with the
instructions given in the mode switching table.

Read the Service Instructions for the Brake Systems
carefully before use.

resultar en accidentes peligrosos. Asegúrese de
seleccionar el modo de acuerdo con las instrucciones
indicadas en el cuadro de cambio de modo.

Leer cuidadosamente las instrucciones de servicio
del sistema de freno antes de usarlo.

ADVERTENCIA

Ce levier de frein est équipé d'un dispositif de
commutation de mode qui le rend compatible avec
les freins V-BRAKE, les freins à étrier, les freins
cantilever et les freins à rouleau. Si un mode
incorrect est sélectionné, la force de freinage
obtenue sera excessive ou insuffisante, ce qui risque
de causer des accidents graves.
Veiller donc à sélectionner le mode conformément
aux instructions données dans le tableau de
commutation de mode.

Avant l'utilisation, lire attentivement les instructions
de montage des systèmes de frein.

AVERTISSEMENT

Esta alavanca de freio está equipada com um
mecanismo de mudança de modo para torná-la
compatível com freios V-BRAKE, freios de pinça,
freios cantiléver e freios de rolete. Se for
selecionado o modo incorreto, poderá ocorrer uma
força de frenagem excessiva ou insuficiente, o que
pode resultar em acidentes perigosos.
Certifique-se de selecionar o modo de acordo com
as instruções dadas na tabela de mudança de modo.

Leia as instruções de serviço para o sistema de
freios cuidadosamente antes do uso.

ADVERTÊNCIA

Questa leva del freno è dotata di un meccanismo di
selezione della modalità che la rende compatibile con
i freni V-Brake, a pinza, a Cantilever e a rullo. In caso
di selezione di una modalità non corretta, potrebbe
essere applicata una potenza di frenata eccessiva o
insufficiente ed entrambi i casi potrebbero essere
causa di seri incidenti.
Selezionare la modalità in base alle istruzioni
descritte nella tabella di selezione della modalità.

Prima dell’uso leggere attentamente le Istruzioni
relative all’Assistenza per il Sistema Frenante.
