There doesn't seem to be any difference from the pictures, it's just that the ventilation disc is very large in size, while the brake caliper is very large in size; The visual impact is still very strong. However, this is only a brake disc after all, can it have such high value? In fact, carbon ceramic brake discs are not uncommon and are used in many high-performance cars; There are also cars such as the Jike 001 FR that have been used in domestic brands, and the Xiaomi SU7 Ultra is not as "pioneering" as some car enthusiasts claim. However, one thing cannot be denied, that is, the manufacturing cost of this type of brake disc is indeed very high.

Carbon fiber reinforced silicon carbide based composite material "is the foundation of carbon ceramic brake discs, which have been on display for 25 years but are rarely used in vehicles; The reason is that the manufacturing cost of this composite material is high. Through the application of carbon fiber, this brake disc will have higher mechanical strength and fracture toughness, as well as extremely strong high-temperature resistance.

The braking and deceleration principle of a vehicle is very simple, summarized in one word as "friction

By using a brake cylinder to apply force and push the brake pads into contact with the brake disc, the friction between the two can produce a "reverse effect" with the brake disc. The brake disc rotates at the same speed as the wheels, and stopping the brake disc by "rubbing" is equivalent to stopping the wheels. However, the process of friction not only causes wear, but also generates heat energy, so prolonged braking will inevitably result in extremely high temperatures. High temperature will reduce the friction coefficient between brake pads and brake discs, causing a linear decrease in braking force until it disappears, which is brake failure.
