One of the most important roles in the design of the brake system is the brake caliper. The safety of movement by car often depends on this mechanism. When the brake disc is compressed, the brake pad transfers the received load to the caliper, and it subsequently transfers it to the parts of the chassis of the car.
Structurally, the brake caliper can be represented as two interconnected parts. One of which is a fixed bracket attached to the trunnion with bolts. And the second is a movable brake caliper attached with bolts and a repair kit to the bracket. And in order for the pads to be free to decompress when the pedal is released, the movable caliper has the ability to move horizontally.
The brake caliper has a cylinder that compresses the brake pads when the brake pedal is pressed, and the caliper is connected to the vehicle's hydraulic system. Due to this, all loads are not transferred directly to the "chassis", but through the caliper to the bracket and other parts. The process itself can be represented as a transformationkinetic energy into heat. What happens due to the friction of the pads and disc, as well as the friction of the wheels on the road surface.
A drum brake can be considered an analogue of a caliper, but this type is rarely found in modern cars. And the drum brake gained unpopularity due to the fact that it often fails, and is also less effective than a caliper. Therefore, today, even on non-driving wheels, only a brake caliper is used.
This design has become widely used in the automotive industry in the last decade. And the merit of this, of course, is the indisputable advantages of this system: the simplicity of the design itself, high braking efficiency, ease of maintenance, and durability. Another advantage of the caliper is the low weight of the structure, and this is achieved due to the small amount of metal used in the manufacture.
The brake caliper, in fact, has only one drawback: it is its openness, that is, in rainy weather, water can get on the brake disc, which reduces braking efficiency. But it is precisely due to its “openness” that this mechanism does not overheat, which is rather a plus.
Brake caliper very rarely fails. And its maintenance consists only in replacing the brake pads and lubricating the repair kit of the caliper itself. Rarely there are cases when it is necessary to replace the brake cylinder repair kit. When repairing, due to the simplicity of its design, the brake caliper does not require large financialcosts.
Today, the brake caliper is used in almost all modern cars: cars, trucks, SUVs, as well as in construction equipment. After all, this is reliability, combined with simplicity of design, which greatly simplifies its operation. Most likely, for more than one decade, humanity will not invent a worthy replacement for the brake caliper.

Not always an inexperienced driver manages to cope with the car and quickly reduce the speed. You can prevent skidding and blocking of the wheels by intermittently applying the brake. There is also an ABS system, which is designed to prevent dangerous situations while driving. It improves the quality of grip with the roadway and maintains the controllability of the car, regardless of the type of surface

The internal combustion engine works stably only under a certain thermal regime. Too low a temperature leads to rapid wear, and an excessively high temperature can cause irreversible consequences, up to jamming of the pistons in the cylinders. Excess heat from the power unit is removed by the cooling system, which can be liquid or air
