Different types of brake discs
Whether ventilated, one-piece, cast / steel, carbon or even ceramic, there are many different types of disc brakes. Discover or rediscover them by observing each of the advantages and disadvantages.
Difference between full and vented disc
The difference is quite simple, the easiest way is to recognize a full disk, a blank disk without any features. A ventilated drive looks like two hard drives stacked on top of each other with a gap between them to improve cooling (it can indeed dissipate through the center of the drive as well). As a rule, the front brakes are ventilated, and the rear brakes are filled for cost reasons (the rear brakes are less loaded, so there is no need to install ventilated discs).

Here is a clipping version ventilated
Some discs full heats up very quickly ...
Perforated discs
Therefore, they should not be confused with ventilated discs, even if in the end the goal and principle remain the same: better cooling by "ventilating" the discs.
Small holes accelerate cooling by allowing air to pass through them.
Ceramic and carbon rims
Discs made from these materials are rare, a set of discs can cost from 5000 to 10 euros, and it’s immediately clear why ... The advantage of these two processes is again related to heating. These two technologies help maintain strong braking performance even with hot discs. Thus, the tolerance is much higher, which means that when the cast iron discs are hot and unusable (an obligatory break to allow it to cool), the carbon and ceramic brakes will continue to be a toy in the chain. In addition, cast iron versions can quickly deform in the event of thermal shock, and the metal becomes ductile. Heavy highway traffic can easily jeopardize your new steel rims.
Please note that ceramics is an exceptional material that is used in many areas, including aerospace. If you heat an inch-thick ceramic plate to a few hundred degrees on one side, you can still put your hand on the other side without getting burned. No wonder it serves as a heat shield for spacecraft.
In addition, ceramic and carbon brakes must be heated to be effective (especially for carbon), which is actually not the case on the cast iron / steel side. And then there are recordings in which two materials are mixed.
