use, so don’t touch a disc brake rotor until it has had plenty of time to cool. Remember
that brake pads in all brake types will wear out, which will ultimately reduce their
efficiency. For information on how to operate and maintain your brakes and when
to replace the brake pads see the brake manufacturer’s operation and maintenance
manual. If you have not been provided with the manufacturer’s instruction manual,
contact your dealer or the brake manufacturer. When replacing worn or damaged parts
the manufacturer-approved genuine spare parts are to be used only. Brake controls and
features
It’s vital for your safety to learn and remember which brake is controlled by which
brake lever on your bike. Acquaint yourself with the setup of your brakes by alternately
squeezing the left and right brake lever and observing which brake lever activates the
front brake, and which one activates the rear brake. You should be able to reach the
brake levers with your hands and squeeze them easily. If you find out that your hands
are too small to do so, you should consult it with your dealer before riding the bike. In
some models the lever reach may be adjusted, or you may need a different brake lever
design.
OPERATION OF THE BRAKING SYSTEM
The bicycle braking system’s function is based on friction between two braking surfaces.
To assure its proper functioning you should maintain the rims, brake pads, disc rotor
and calliper clean and free of dust, dirt, grease, lubricants, waxes and polishes. There
are special chemical cleaners available on the market designed specifically for cleaning
these surfaces. Bicycle brakes have been designed to control the speed of your bicycle
by reducing it or preventing the bicycle from moving. The maximum breaking force for
each wheel is achieved just before the moment the wheel stops rotating (“locks up”)
and starts skidding. The instant it has begun to skid, the most of your bike’s stopping
power and all directional control is lost. Therefore, it is necessary to learn how to slow
down your bike and bring it to a halt smoothly avoiding a wheel lockup.
To do so, you should learn a progressive brake modulation technique so that you could
be able to precisely and accurately control the amount of clamp force on a rotor with
a given amount of lever input. Instead of pushing the brake lever abruptly, squeeze
it slowly, and gradually increase the braking force. The instant the wheel begins to
lock up, slightly release pressure to keep it rotating. You should learn how much brake
lever pressure is needed for each wheel at different speeds and on different surfaces.
Reducing the bike speed by applying one or both brakes will transfer the weight to
the front wheel as the rider’s body continues at the speed at which it was going. Heavy
braking will result in the transfer of weight around the front wheel hub, which may send
the rider’s body flying over the handlebars. Greater brake pressure is needed for a wheel
burdened with heavier load to lock up, whereas a wheel burdened with less weight
will lock up with less brake pressure applied. Thus, when your weight is transferred
forward when the brakes are activated, you should move your body backwards in order
to transfer weight to the back, simultaneously decreasing the rear braking force and
increasing the front braking force. It is especially important when you are descending.
