SERVICE INSTRUCTIONS
The brake arch (BR-6403, BR-1055,
BR-A550, BR-A500) must be used as
a set with the brake lever (BL-6403,
BL-1055, BL-A550, BL-A500) and the
Shimano SLR outer cable.
No other combination can be used.
Before use, read these instructions carefully, and follow them for correct use.
Notes
elf, due to the connection arrangement of the cable, the efficiency of
transmission of force decreases and the return of the arch is poor, turn the
sleeve 180° as shown in the illustration, so as to increase the spring force.
Note, however, that brake levers other than the SUPER SLR cannot be used,
even though the spring force is increased.
¿ Turn the
sleeve
180°.
