Hydraulic Disc Brakes (General)
The most striking feature of hydraulic disc brakes is that they combine out-
standing braking effect with good weather resistance. They respond a lot faster in
wet conditions than rim brakes do and achieve their normal high braking power
within a very short time. They also require fairly little maintenance and do not wear
down the rims as rim brakes do. One drawback of disc brakes is that they tend
to be noisy.
The brake levers can usually be adjusted to the size of your hands, allowing
you to operate the brakes optimally.
In most cases this is done by means of a small Allen bolt located directly at the
hand lever. Keep in mind that you may need to readjust the brake pads, as well. Be
sure to read the operating instructions of the brake manufacturer on our website
at www.stevensbikes.de/manual
Note:
Under different
conditions, e.g. in wet
conditions, disc brakes
tend to be noisy. These
noises are normal and
have technical reasons.
As long as the opera-
tiveness of the brake is
not impaired there is no
reason for concern.
Danger:
Disc brakes get hot in use. For this reason do not touch the brakes directly
after stopping, especially after a long downhill ride.
Caution:
Manufacturers of hydraulic disc brakes deliver their products with detailed
instructions. You find them on our website at www.stevensbikes.de/manual.
Be sure to read them carefully before you dismount a wheel or do any
maintenance work.
Note:
New brake pads have to be bedded in before they reach their optimal
braking performance. For this purpose, accelerate the bicycle 30 to 50
times to around 30 km/h (18 mph) and bring it to a halt each time by
braking forcefully. This procedure is finished, when the force required at
the lever for braking has stopped decreasing.
Danger:
Keep oil or cleaning agent off the brake pads. If, despite all precaution, it
does happen, you have to replace the brake pads, as the functional condi-
tion of soiled brake pads can no longer be restored.
Danger:
Disc brakes can only be mounted on bicycles with a solid disc brake
mount. Do not use an adapter for mounting.
Checking and Readjusting Hydraulic Disc Brakes
Check the hoses and connections regularly for leaks while pulling on the lever.
If hydraulic oil or brake fluid leaks out, you should see your STEVENS dealer imme-
diately, as a leak can render your brakes ineffective.
Make sure that you have always a clearly defined pressure point when pulling
the brake lever. If this is not the case, stop cycling and contact a STEVENS dealer
immediately. The hydraulic disc brakes from Magura and Shimano have a fully
automated brake pad wear adjuster. It ensures that the brake lever travel does not
change with the wear of the brake pads and there is therefore no need to readjust
the brake. Check the thickness of the brake pads regularly. The overall thickness
of the pads should not be less than 2.5 mm.
Check the pads for wear by inspecting the thickness of the braking material
attached to the backing plate within the brake calliper or view through the window
on the upper side of the calliper. If there is approximately 1 mm of material left on
each brake pad, remove the pads according to the manufacturer’s instructions on
our website at www.stevensbikes.de/manual and check them thoroughly.
With a thickness of 0.5 mm (measured without holder) the brake pads have to
be replaced at the latest.

Danger:
Do not open the brake
hoses. Leaking out brake
fluid is very unhealthy
and aggressive to the
coating.
Danger:
When you state a
changed pressure point
when braking forcefully
or when you have to
pump with the lever
repeatedly to achieve
a braking effect, stop
cycling and contact your
STEVENS dealer.
Danger:
Open connections and
leaky hoses result in a
severely reduced brake
performance. If you
find leaks in the brake
system or bent hoses,
contact your STEVENS
dealer. Risk of accident!
