Brakes - Specialized Roubaix Comp Road Manual De Instrucciones

WARNING: If you can fully close the cam
lever without wrapping your fingers around
the seat post or a frame tube for leverage,
and the lever does not leave a clear imprint
in the palm of your hand, the tension is
insufficient. Open the lever; turn the tension
adjusting nut clockwise a quarter turn; then
try again.
There are three general types of bicycle brakes: rim
brakes, which operate by squeezing the wheel rim
between two brake pads; disc brakes, which operate
by squeezing a hub-mounted disc between two brake
pads; and internal hub brakes. All three can be operated
by way of a handlebar mounted lever. On some
models of bicycle, the internal hub brake is operated by
pedaling backwards. This is called a Coaster Brake and
is described in Appendix C.
WARNING:
1. Riding with improperly adjusted brakes,
worn brake pads, or wheels on which the
rim wear mark is visible is dangerous and
can result in serious injury or death.
2. Applying brakes too hard or too suddenly
can lock up a wheel, which could cause you
to lose control and fall. Sudden or excessive
application of the front brake may pitch the
rider over the handlebars, which may result
in serious injury or death.
3. Some bicycle brakes, such as disc brakes
(fig. 11) and linear-pull brakes (fig. 12), are
extremely powerful. Take extra care in
becoming familiar with these brakes and
exercise particular care when using them.
4. Some bicycle brakes are equipped with a
brake force modulator, a small, cylindrical
device through which the brake control cable
runs and which is designed to provide a more
progressive application of braking force.
A modulator makes the initial brake lever
force more gentle, progressively increasing
force until full force is achieved. If your bike
is equipped with a brake force modulator,
take extra care in becoming familiar with its
performance characteristics.
