19.5 Brakes
Normally there is one disc and one rim brake
fitted to the product. Where possible, both
brakes should be operated simultaneously and
the braking requirement reduced by driving in a
way that anticipates the requirement to reduce
speed if necessary.
Please note that the braking effect can be
strongly reduced by one or all of the following
conditions:
Worn tyre profile
Soiled and wet tyres
Wet, soiled, loose and uneven ground
Dirt and wetness on the brakes and brake
surfaces
Decreasing weight load
19.5.1 Rim and disc brakes
The brakes are operated manually using the
brake lever.
Figure 34: Brake lever
In the event of abrupt hard braking, there
is a risk that you might fall forward with your
upper body and thereby cause injuries to your-
self.
With rim brakes: Please make sure that
the braking surfaces on the rim and the brake
pads on the rim breaks do not come into con-
tact with oils or greases which could otherwise
impair the braking effect.
With disc brakes: At regular intervals,
check that the brake pads and discs are free
from grease, oil or other contamination. In
addition, check the thickness of the brake disc.
The minimum thickness is printed on the brake
disc. In addition, the brake pad thickness must
be checked with a measuring calliper. The
minimum pad thickness plus support material
is 2.5 mm.
If equipped with V-brake rim brake as
service brake: The setting screw on the brake
lever of the V-brake rim brake must be well
locked. In addition, this setting screw on the
brake lever must always be checked for tight-
ness.

You can find further information in the brake
manufacturer's instructions.
19.5.2 Back-pedal brake for hub drives
A back-pedalling brake is already integrated
into the Shimano Nexus hub gears. This brake
is operated by moving the cranks against the
acceleration direction. The brake force applied
is adjusted by the strength of the backwards
movement of the cranks.
For more information, please see the instruc-
tions provided by the brake or gear manufac-
turer.
19.5.3 Parking brake
An
aluminium bracket
is attached to the bot-
tom bracket support as a parking brake. With
it, one of the two brakes can be used as a
parking brake. For this purpose, the aluminium
bracket is clamped over the grip and the brake
lever while the brake lever is depressed.
