Wear and maintenance
To a certain extent, the wear of the brake pads can be
compensated for directly at the brake lever. Unscrew
the knurled lock nut on the bolt through which the
cable enters the grip and then unscrew the bolt until
the lever has the desired travel
(f)
. Retighten the lock
nut by taking care that the slit of the bolt head does
not face upward or forward, as this would permit an
unnecessarily high amount of water or dirt to enter.
After readjusting check the functioning and make
sure the brake pads do not drag when releasing the
brake lever and spinning the wheel.
Repeated readjustment at the brake lever makes the
arm on the brake caliper change its position. This can
make the brake less effective and result in a complete
brake failure in an extreme case. Risk of an accident!
Some models offer further ways of adjusting the
brakes directly at the brake caliper, though this
requires a certain amount of skill. Read the instruc-
tions of the brake manufacturer on this CENTURION
CD-ROM carefully before adjusting the brake. If you
are in doubt or if you have any questions, contact
your CENTURION dealer.

Repeated readjustment at the brake le-
ver can drastically reduce the maximum
braking effect.

Read in any case the instructions of the
brake manufacturer on this CENTURION
CD-ROM carefully before removing the
wheel or doing any maintenance work. Improper
operation can lead to brake failure.
Roller, drum and back-pedal brakes
These types of brakes have an enclosed design;
brake pads and surfaces inside the hub body
are largely protected against the influences of the
weather. The braking force is transmitted through
cables from the levers to the brakes. As rear brakes
they are mostly connected to an internal gear hub
(g)
and sometimes they are operated by back pedaling.
With back-pedal brakes maximum braking force is
achieved by stepping on one of the pedals in its rear-
most position with the cranks horizontal. With internal
gear hubs from SRAM braking force is increased
when having shifted to a lower gear.
The risk of overheating is particularly high with these
brake systems. Brake overheating occurs on pro-
longed (steep) downhill rides with permanent brake
dragging. Brake fading is a result thereof which, in
extreme cases, can lead to brake failure.
