Disc Brakes - Scott TIME TRIAL MACHINE Owner's Manual

DISC BRAKES

Operation and wear
The most striking feature of disc brakes (e) 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 mainte-
nance and do not wear down the rims as rim brakes do. Disc brakes consist of
the brake calliper, the rotor, the brake lines (hydraulic) or cables (mechanical) 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 can accelerate wear on both brak-
ing surfaces. Depending on the manufacturer and the model there are different
ways of checking the brake pads and rotors for their wear limits.
WARNING
New brake pads have to be bedded in before they reach their optimal
braking performance. Accelerate your SCOTT bike about 30 to 50 times to
around 30 kmh and bring it to a halt each time. This procedure is finished,
when the force required at the lever for braking has stopped decreasing.
Dirty brake pads and rotors can lead to drastically reduced braking power.
Therefore, make sure the brake remains free of oil and other fluids, especial-
ly when you clean your SCOTT bike or grease the chain. Dirty brake pads
can under no circumstances be cleaned, they must be replaced!
Rotors can be cleaned with special brake cleaners or with warm water and
mild soap.
Unusual noises (scratching, chafing etc.) during braking and/or a noticeable
change of the braking force (stronger or weaker) are indications that the
brake pads are soiled or worn down (f). Check the brake pads and replace
them, if necessary. Otherwise you risk further damage, e.g. to the rotor,
or even an accident due to brake failure! If you are in doubt, contact your
SCOTT dealer.
