The two-circuit brake system is divided into two parts, and each part works independently of the other. This means…
 If one of the two circuits malfunctions, the other healthy circuit works normally

These modern brakes increase the safety of the car and are a feature found in all cars except old-style cars

Modern cars now have hydraulic brakes, which means greater braking power
 You move from pedal to brake without stomping hard
 This is due to its brake fluid, i.e. hydraulic fluid

What if there is a brake malfunction?  How did he discover that?

You can test or try the brakes in one of the following ways:

When pressing the brake, the pedal takes a long time to go down
 This often indicates wear and the problem should be checked

If the pedal continues to decline slowly even when it reaches the bottom, this often indicates a leak and the problem must be checked
 If during braking you feel that the pedal vibrates unusually, this often indicates the presence of air in the brake system and the problem must be checked.

I also advise that the brakes be tested and tested every once in a while because of the importance of this matter.  Brakes are greatly affected by the presence of water and humidity
 When washing the car, the first step you should take is to make sure that the brakes are working properly.

Brake fluid and its importance

Over time, brake fluid absorbs water, moisture, and dust, and this leads to it losing its functions and quality
 Therefore, I recommend changing the oil every two years at most to ensure that there are no problems and to guarantee the quality and characteristics of the oil

Brake fluid can

Servo system

The servo system is important and helps in braking
 With the servo system, you need less pressure on the pedal to brake
 Also, the system does not work unless the car is running

You can verify that the servo system is working through the following steps:

Press the brake pedal several times until it becomes high and solid, meaning it does not go down
 Keep your foot on the pedal and start the car
 You will notice that the pedal has decreased, which means that the system is working well

Manual brake

The hand brake is present in all cars and is also important and you can use it to prevent the car from rolling.
 
 The hand brake should not be used when the weather is very cold as it deflates and freezes

 This makes moving the car difficult, and in some cases it may break
 Not using the manual brake permanently or for long periods may make it uneven

You can check the manual brakes in the following ways:

While the car is parked, start the car while raising or activating the hand brake
 Try to move the car forward very quietly
 You will notice that the car does not move and rise forward. This is because the brakes are activated or the brake hand is raised. This means that it is working well.
 
 You can also lift or activate the handbrake and reverse very quietly
 You will notice that the car rises from the back and falls from the front
 This is because the brakes are activated or raised, which means they are working well

If the car moves forward or backward in one of the cases I mentioned
 This means that it is inefficient or completely broken, and the problem must be checked and fixed
