MANITOU
Wire
➀
If bolt
tries to loosen (turn in
the counterclockwise direction),
force is applied via the wire to turn
➁
bolt
in the tightening direction
(clockwise). However, bolt
cannot turn any further in the
tightening direction.
Accordingly, this prevents bolt
from turning in the loosening
direction because it is also
connected via the wire.
If either one of the bolts tries to
loosen, this causes a force to be
applied to the other bolt to turn it
in the tightening direction. In
other words, this system prevents
the bolts from loosening.
For C-shaped guides and the usual type of cable
stoppers, use the special Shimano cable supporter
(sold separately) to secure as shown in the illustration.

Tightening torque:
0.3 - 0.5 N·m {2.7 - 4.4 in. lbs.}
Operate the brake lever several times and check
whether the brakes operate normally or not. Also
check that there are no oil leaks visible.
Maintenance
Brake pad replacement
Note:
Disc brake system is designed so that as the brake
pads become worn, the pistons gradually move
outward to automatically adjust the clearance
between the rotor and the brake pads.
You need to push the pistons back to their original
positions when replacing the brake pads.
