Modification and function of brake caliper and brake pad
Brake calipers and brake pads are the terminal executive parts of
braking. Therefore, the modification of brake calipers and brake
pads can have an impact on the improvement of braking force.
Although it is very effective, there are still some precautions in
the modification process. Let's have a look.
Refitting and replacing a set of large, multi piston brake calipers
can directly improve the braking performance. If the brake caliper
becomes larger, the total area of the brake pad will be larger
accordingly; The more brake caliper pistons, the more uniform the
pressure and friction temperature applied to the brake pads will
be, and the total area of the piston can be increased. Of course,
the braking efficiency will be improved.
Brake caliper
The modified brake calipers are divided into non original and
original. Non original brake calipers are almost all racing
products. The multi piston design is adopted, which must be matched
with the special adapter support commonly known as "bridge" during
installation. In addition to the large pressure area of the piston,
the weight of this kind of products is particularly light, which
can reduce the load of the suspension and accelerate the activity
speed of the suspension. If used with a brake disc with a larger
diameter, the light caliper can offset the increased weight of the
brake disc. The original products usually adopt the design of a
larger diameter or multiple caliper pistons.
Brake pad
Modification of high-performance brake pads the friction of brake
pads is the most important. Most high-performance brake pads are
made of metal (cast iron, aluminum alloy) and carbon fiber. The
performance of brake pads mainly depends on the formulation of
materials, because the selection of brake pads requires material
information. Buying brake pads is very particular. Some car owners
use the brake pads of pure racing cars, but they get worse braking
effect than the brake pads of the original car. The reason is the
temperature problem of the brake pads. Ordinary vehicles simply
can't reach the high temperature of racing car braking, so the
brake pads of pure racing cars can't exert its high braking force
at high temperature, so they can't achieve the due effect.
When selecting high-performance brake pads, be careful not to pay
too much attention to ultra-high temperature and friction
coefficient. If the friction coefficient is too high, the braking
action of the vehicle when driving at a slow speed will become too
sensitive. Each touch of the pedal will make the passengers on the
vehicle look up and close back. At the same time, it will also
cause excessive wear of the brake disc and affect the service life.
The high-temperature resistant brake pad can not play a
high-performance braking force at low temperature, and the effect
will be greatly reduced. Therefore, the modification of brake
caliper and brake pad varies from vehicle to vehicle and from
driving habits.
