As the brake pads wear down, the pressure point
moves towards the handlebar grips. Make absolutely
sure you cannot pull the brake lever all the way to
the handlebar grip. Most brake models are, how-
ever, fitted with a bolt or a small knob at the brake
lever unit to compensate the wear. Observe the
operating instructions of the brake manufacturer on
this CENTURION CD-ROM. If you are in doubt or if
you have any questions, contact your CENTURION
dealer.

Read the instructions of the brake man-
ufacturer on this CENTURION CD-ROM
carefully before removing the wheel or
doing any maintenance work. Improper opera-
tion can lead to brake failure.
Disc brakes
Functioning and wear
The most striking feature of disc brakes
(g+h)
is
their outstanding braking effect. 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 require little maintenance and do not
wear down the rims as rim brakes do. Disc brakes
consist of the brake caliper, the rotor, the brake lines
or cables as well as the brake lever unit. Actuating
the brake lever compresses the hydraulic pistons
through hydraulic pressure or mechanically, pushing
the brake pads against the rotor.
The friction generated by braking causes wear to the
brake pads as well as to the rotors. Frequent rides in
the rain and dirt and over hilly terrain can accelerate
wear on both braking surfaces. Depending on the
manufacturer and the model there are different ways
of checking the brake pads and rotors for their wear
limits.
G
New brake pads have to be broken in
until they reach their optimal braking
power. Accelerate your CENTURION
bike about 30 to 50 times to around 30 kmh and
bring it to a halt each time. This procedure is fin-
ished, when the force required at the lever for
braking has stopped decreasing.
G
Disc brakes get hot in use. For this rea-
son do not touch the rotors directly after
stopping, especially after a long down-
hill ride.
G
Dirty brake pads and rotors can lead
to drastically reduced braking force.
Therefore, make sure the brake remains
free of oil and other fluids, especially when you
clean your CENTURION bike or grease the chain.
Dirty brake pads cannot be cleaned under any
circumstances, they must be replaced! Rotors
can be cleaned with special brake cleaners or
with warm water and mild soap.
