For many drivers, the brakes of a vehicle are simply a lever and a pedal that are activated when they want to or must stop. They do not know that beyond what they see there is a real system that has been perfected over time thanks to the inventiveness and recursion of modern man.

Since the beginning of the 20th century, when a single guaya braked the vehicle in its entirety and it was the driver who had to use all his strength to stop it, until today, when a vehicle brakes thanks to devices and sensors of the highest technology, the brake system has been the cornerstone of the advances that are presented in the world of cars. Know your main axes of operation and what you need to know to have some brakes 1 A.

By means of physics, many of the processes that describe the braking system of a vehicle can be explained.

The principle of basic operation in the brakes of a car is friction, which is that when a body comes into contact with the other in different directions appears a force called friction that is opposed to the movement of the same body. This force depends on two major factors: The contact area between the bodies and the force applied between them.

In a vehicle, the contact area appears between the braking elements of the car (contact area between discs and pads, and in some cases between belts and bells), in addition to the contact area between the rims and the surface on which it circulates. the vehicle.

Correct inflation pressure means that the tread enters in perfect contact with the asphalt, ensuring that all the braking forces are transmitted and the vehicle stops faster.

Do you think that the force you make with your foot when braking is enough to contain the movement of your car at the speed you’re going?

To be able to stop a vehicle with only the foot it is necessary that there are elements that amplify the force. To do this, use the brake booster, which multiplies the force you make when operating the pedal. In this way, the driver is expected to make his least effort when braking.

The mechanical advantages that a vehicle uses to multiply its braking force are: the lever effect and the hydraulic force. The first is that “having a point of support, the greater the distance that the body that must move is, the less force I must make to move it”. The hydraulic force, on the other hand, “consists in that when force is made in an area, the resultant of it will be proportional to the area where it will be applied”.
