The brake system is the most important unit in the operation of every modern car. The safety of the driver and his passengers directly depends on the efficiency of its work and good condition. Its main function is to control the speed of the vehicle, braking and stopping as needed.
Modern cars are equipped with three types of these devices:
- Working brake system.
- Parking.
- Reserve.
And now about all this in more detail. So, the first system is working for us. This device is designed to effectively reduce the speed of the car, as well as to stop it completely. It can be activated when the vehicle is moving (reducing speed in front of a dangerous object or when passing maneuvers).
The second brake system is parking. It is intended to hold the car in place (for example, so that the car does not roll down in a parking lot or slippery road).
The next element is a reserve one. These brake systems are activated only when the first fails and ceases to function. Most often, it is an autonomous part of a working device.
Brake device in action
This element plays an important role in this car system. It serves to control the speed of the vehicle when it needs to slow down or stop. The operation of the brake mechanism is carried out using a special friction material. The latter creates a friction force, due to which the disk or drum slows down its movement. Accordingly, in this case, the car begins to reduce its speed. How high this value is depends on the force that acts on the brake pads and disc.
The brake system (working) is installed in the wheels of the car themselves. As we said above, they can be either disc or drum. The latter consists of two main elements. These are the brake drum (rotating part) and pads (fixed part). More modern is the disc brake system. It consists of similar parts, only instead of a drum there is a disk.
As a rule, all modern cars, especially foreign cars, are equipped with just such devices. The diagram of the disc brake system indicates that the pads in this mechanism are located inside the caliper on both sides of the rotating disc. The working cylinders are installed here in the grooves of the caliper (the part itself is mounted on a bracket).
When braking, they clamp the pads to the brake disc, due to which there is a sharp decrease in speed. However, at the same time, the entire system experiences cardinal temperature loads, which occur due to the friction force. And so that the pads do not burn out and do not stick to the disk, the wheels have special ventilated holes through which air flows into the system.
This is how the braking system of a modern car works.
