Disc
brakes
Disc
brakes are also used on high performance bikes. The system shown
is a mixed mechanical/hydraulic design, and perforations on the disc face
help in the removal of water and in brake cooling.
The disc is attached
to the wheel hub carrier and the hydraulic pistons that push the brake
pads onto the disc are attached to the bike frame. The hydraulic actuator
is connected to the hand controls and the high-pressure brake fluid is distributed
to the brakes through the lines seen in the diagram. This type of system
permits better modulation of the brake force and requires less adjustment
than a cable systems.
The use of hydraulic actuation is not restricted
to disc brakes, and commercial hydraulic systems for cantilever style brakes
are available. |
