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 en-
ters 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 le-
ver 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 cer-
tain amount of skill. Read the instructions of the brake
manufacturer on this MERIDA CD-ROM carefully before
adjusting the brake. If you are in doubt or if you have any
questions, contact your MERIDA dealer.

Repeated readjustment at the brake lever can
drastically reduce the maximum braking ef-
fect.

Read in any case the instructions of the brake
manufacturer on this MERIDA CD-ROM care-
fully 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 pro-
tected 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 prolonged
(steep) downhill rides with permanent brake dragging.
Brake fading is a result thereof which, in extreme cases,
can lead to brake failure.
