Removing the hydraulic rim brake:
• If your system features a brake quick release,
remove the brake unit according to the instruc-
tions supplied by your manufacturer.
• If you do not have a brake quick release, de-
ate all of the air out of the tyre
Hydraulic rim brakeBrake pad wear
The brake pads for rim brakes are almost all t-
ted with grooves or notches.
The grooves and notches serve in part to help
identify the wear level of the brake pads. If these
can no longer be seen, you should replace the
brake pad.

• The wheel can be removed without any further
preparation.
• Please note: when tting the wheel, the disk
must be slotted between the brake linings of
the brake calliper and ultimately be centred
without contact.
Vapour bubbles in the disc brakes
Mechanical oder hydraulic disc brakes
Avoid permanently braking for long
periods, as can be the case during
long, steep descents. The formation
of steam bubbles and total failure of the brake
system might otherwise result. This may
cause severe falls and injuries.
The brake lever may not be activated when
the bicycle is lying on its side or turned up-
side down. Otherwise air bubbles can enter
the hydraulic system which could cause the
brakes to fail. Test after each journey whether
the pressure point of the brake feels softer
than it did before. Slowly activate the brake
several times. This allows the braking system
to discharge any bubbles. You may not ride
on when the pressure point remains soft. A
specialist retailer has to discharge the air from
the brake system.
You can avoid this problem by apply-
ing the brake lever before transport
and then xing it in this position using
a strap. This prevents any air from entering
the hydraulic system.
Normal operation wears down brake
rubbers and brake pads. You should
therefore regularly check the condi-
tion of your braking system and brake pads!
Replace worn brake pads and rubbers in
good time!
Ensure that rims and brake discs are clean
and free of any oil!
Various versions of disk brakes are
available for racing and cyclo-cross
bikes. Always read the enclosed in-
structions from the component manufacturer
before the rst ride. Make sure you practice
and get used to operating the brakes on safe
terrain before going on your rst bike ride!
