Brakes, brake levers and braking systems
It is possible that brake fluid can escape from
the system due to leaky cables and connec-
tions. This can negatively impact the effec-
tiveness of the brakes. Before every ride you
should therefore check whether the cables and
connections are leaking at all.
Do not ride with your FLYER if fluid is es-
caping from the braking system. Please allow
a specialist retailer to undertake repair work
on this part immediately. The danger of your
brakes failing in this condition is very high.
You may NOT ride either if the brake pads
or disc/rim are tainted with grease. Dirty pads
have to be replaced, greasy rims and brake
discs have to be cleaned.
23.5.2 Formation of vapour bubbles
Avoid permanently braking for long periods, as
can be the case during long, steep descents. A
better approach is alternating between using
the front and back brake, as this allows each
brake to cool in sequence. Brake directly be-
fore sections where you have to ride slowly.
This helps you to avoid overheating the
brakes. If the brakes are heated over the boil-
ing point, vapour bubbles can be caused which
will in turn cause a total failure of the braking
system, as no braking pressure can be built up.
23.5.3 Cleaning the brakes
When you come to cleaning the braking sys-
tem, please first read the instructions provided
by the component manufacturer. The braking
system can be cleaned in the same way as
the rest of the bike with warm water and mild
cleaning fluid, e.g. washing up liquid. You can
use a sponge or a soft cloth.
The brake discs and brake surfaces of rims
should be specially cleaned with isopropyl al-
cohol. Your FLYER retailer can recommend a
suitable cleaning fluid for this.
It is essential to test the brakes
every time you change the brake
setup. To do this, pull on the
brake lever and push the pedelec strong-
ly forwards. Only ride your pedelec if you
are able to safely stop it.
Ensure that the brake lever is
not applied when your FLYER is
being transported on its side or
upside down. Otherwise air bubbles can
enter the hydraulic system which could
cause the brakes to fail. After transport-
ing the bicycle, check if the pressure
point of the brakes seems different than
it was before.
If the brakes feel softer than before,
apply the brakes slowly several times.
This allows the braking system to dis-
charge any bubbles. If the brakes remain
soft, please refrain from riding. A spe-
cialist retailer has to discharge the air
from the brake system.
You can avoid this problem by
applying the brake lever before
transport and then fixing it in
this position using a strap or a rubber
band. This prevents any air from enter-
ing the hydraulic system.
In particular, brake pads are
subject to wear. Please allow a
FLYER retailer to check these
key parts on a regular basis and replace
any worn parts if necessary.
