There are various braking systems which differ
depending on their areas of use:
• Hub brakes,
• Disk brakes and
• Rim brakes.
The brake systems can be operated mechani-
cally or hydraulically.
23.2 Brake levers
23.2.1 Standard brake levers
Suitable brake levers are installed on your pe-
delec as standard. When you apply the brake
lever, you should not be able to pull it all the
way to the handlebar grip, even under heavy
braking. Regularly check the performance of
the brakes. The brake performance is no long-
er sufficient if you can roll your pedelec slightly
forwards under braking. In this case, the brake
cables have to be adjusted or the brake pads
replaced by a specialist retailer.
Only use original replacement parts. Oth-
erwise it is possible that the functionality of
your pedelec is impacted or damage could be
caused.
Only use brake pads which match the rims,
as this is the only way to ensure that you have
the right friction combination.
If this is incorrect, the braking distance in-
creases and there is higher wear.
On no account should you allow any oil or
grease to contact the brake pads, as the brak-
ing performance is otherwise substantially
impacted. If the brake pads come into contact
with oil or grease, these have to be replaced.
Brake cables are subject to wear
due to their constant use. Check
the wear level at regular intervals
and allow the brake cables to be replaced
by a specialist if required.
Regularly check the brake cable for
damage. If the cable is rusty or lacerat-
ed, have the cable replaced. If you do not
replace a brake cable in this condition, it
can negatively impact the effectiveness
of the brakes.
All screws have to be tightened
with the correct torque. If the
torque is not correct, the screws
could break or loosen other parts (see
chapter 33.3 “Torques for screwed con-
nections”).
Check the position of the
brake levers before your first
ride.
In hub gear systems, the right brake
lever on the handlebars is generally the
front brake. However, in chain gear sys-
tems, this brake lever is located on the
left side of the handlebars.
If you would like to swap the position
of the brake levers on the handlebars,
please contact a specialist retailer to do
the work.
