“Car brakes burst” in the news. His statement is factually wrong! What happens to brakes that cannot be punctured, such as tires?

What we mean is that bursting the brakes is actually a misuse. Because your brakes are like rubber It is not possible to explode.
So what suddenly happens to these brakes? it does not work And do accidents happen to us?
How does the braking system work? Let’s look at that first.
If we look at the general concept of the braking system and how it works, we can better explain our main topic. Brakes, one of a car’s lines of defense against accidents, are used to stop the vehicle in the event of a malfunction. backup system It works with .
After braking regulations came into effect in the 1970s, vehicles main braking system with two circuits and a parking brake started to be found. In the event of a malfunction in the hydraulic or air braking system, a braking system may fail.
In this case on the dashboard of the vehicle (!) lamp burns. If the driver presses the brake pedal firmly after detecting this warning, the other brake is activated and the vehicle stops. If both fail, this time the parking brake is activated.
What happens if both the handbrake and the dual-circuit main braking system fail and the “brake bursts”?
It would be more accurate to consider this through two systems. First hydraulic brakes Let’s see why it doesn’t work.
Why don’t hydraulic brakes work?
For braking the vehicle of hydraulic oil pressure has been used. With the force exerted on the pedal, the piston of the central cylinder creates pressure. The pressure passes through pipes to the wheel cylinder and braking is done by opening the cylinder pistons.
The main reason why the hydraulic brakes in new generation vehicles do not work is the decrease in hydraulics. Crack or tear in the pressure transmitting pipes have a crack, loosening connection points, cylinder wear and wear of the hydraulic tank will cause the braking system to malfunction.
What causes a malfunction in the drum brake system?
Between brake calipers in drum brake systems clock There is a part. After the movement of the drum towards the brake calipers brake pads contact with the vehicle tire is guaranteed. This is how braking takes place. It is possible to see the drum brake system in old model vehicles or motorcycles.
Between drum and pad coefficient of friction, decreases with temperature. When this temperature, also called ‘fading’, in the brake pads of commercial vehicles increases from 100°C to 400°C, the reduction in braking force is around 60%. This temperature is why the brake pedal does not hold when pressed.
Other things that can cause the brakes to fail or overheat:
Using the brakes to slow downhill can cause the braking system to overheat depending on the weight of the vehicle. That’s why passenger cars use foot brakes. shift downin large vehicles delay system should be used.
One of the things you can do to prevent fading is speed control. With driving training, the driver can become aware of the speed at which he is driving. Naturally speed limiter Other methods that can be used are:
As for hydraulic brakes, in addition to the situations mentioned above, it is necessary to be careful, especially in hot weather. When the temperature is high, hydraulic oil can boil and this makes the braking system ineffective.
Any vehicle that has not been taken precautions and maintained is likely to cause problems. Therefore, braking systems are necessary to avoid disaster. regular check-up should be done.
What is the situation in Germany, one of the largest car manufacturers in the world?
Germany conducted a study between 1984 and 1991 and found that in 20% of commercial vehicles involved in accidents, the cause of the accident was “braking”. This research shows that 57% of technical problems are caused by Lack of vehicle maintenance and improper service It also shows that it is so.
Germany, which has made a name for itself with both its highways and the technologies in its vehicles, is also meticulous about driver licensing. For driver candidates special training on braking Germany, which provides service, also inspects vehicles by stopping them en route for brake maintenance. So it’s not where it is!
Even though it is sad, let’s look at the news using the definition of “brake explosion” and come to the end of our content.
After looking into the technical details, we saw that the phrase “brake burst” was actually wrong. Instead of “brake burst” “not being able to brake” It’s actually the best thing to say. Because there is no explosion in either the hydraulics or the drum brake system.
