to say what part the most expensive car, really hard to say, but what is most important to say car? That must be the brake system! Original buy food on board single-piston floating calipers tired of watching it? The just-concluded Suzhou GT show modified auto show, an array of various brake calipers, brake discs, absolute visual feast. To see what more special brake calipers and brake discs do?
In general we see the brake discs are circular, right? Is there not a party?
do not worry, there really is not circular discs, such as this. This brake disc is called quot; Plum dish quot ;. It is not smooth, rounded edges, but serrated. This is actually the first brake disc to remove contaminated mud on brakes, brakes used on a professional off-road racing or rally car. And now, this shape brakes became standard RS Audi’s high-performance cars, and admittedly a gimmick than practical, but also became a distinctive feature of RS cars.
Speaking of brakes, what is the biggest enemy? Absolutely heat. The working principle is the brakes by brake pads and the brake disc friction, the mechanical energy into thermal energy thereby decelerating the vehicle. However, when the rapid heat accumulation, brakes and brake pads because the surface molecular structure of the temperature change occurs, reducing the friction, resulting in a decline in braking force.
especially for the brake system work more demanding and ultra-performance cars are running, upgrade the brake system has become a priority. So how do against thermal decay? Generally use two methods, one is to enhance the heat dissipation, such as to vent disk, or the cooling air duct; the other is to increase the heat resistant material, such as carbon-ceramic brake discs.
carbon-ceramic brake discs in recent years gradually been known that such carbon fibers and silicon carbide brakes are synthesized at high temperature of 1700 reinforced ceramic composite. Brakes biggest advantage of this material is that it is effective against thermal decay, and it weighs less than half of ordinary cast iron pan, a significant reduction in the unsprung mass. Improve the handling of the vehicle. Well to say the shortcomings,It is a set of brakes may be more expensive than your car.
In addition to carbon-ceramic, there is a tungsten carbide surface of the cover plate to the disk, and thus the manufacturing process is capable of producing a very high strength and durability performance. Braking effect which is almost no difference in the carbon-ceramic brake system, and has the same heat resistance, but it is only one-third the cost of carbon-ceramic, and does not require the use of high-level car brake pads wear, less than the brake dust , after heavy rain and never rust.
a more powerful braking system that allows you to brake later in the corners, and good heat dissipation and thermal properties of the recession make you more confident, not in because the track in brake failure and accidents.
as the highest power components on the car, the brakes start to finish play a vital role.
