Novice car owners, how do you check the brakes yourself?

1. Brake oil

Checking the brake oil is very simple, it only takes two steps.

The first step is to check the height of the brake oil level. Under normal circumstances, the level should be kept between the maximum and minimum tick marks, so that it is more normal.If the brake oil is higher than the highest scale, it will have little effect. At most, the brake oil may overflow when the brake pads are changed.

However, when the brake oil level is lower than the minimum scale, special attention must be paid, because when the brake is pressed, the brake oil in the brake oil can should be added to the brake master pump, which will cause the brake oil level to decrease.If the brake oil is lower than the minimum scale, then there may not be enough brake oil to replenish the master pump when braking sharply. At this time, the brake master pump may enter the air, causing the braking force to decrease.

Fortunately, there is a liquid level sensor on the brake oil tank. When the brake oil margin is reduced to such a level that it may endanger brake performance, the handbrake light on the dashboard will light up, indicating that the driver has insufficient brake oil.But many drivers often mistakenly think that the handbrake switch is broken, so they ignore this important reminder.

The second step is to check the condition of the brake oil. Normal brake oil should be clear and translucent, colorless or light yellow, with no sediment and no stratification.If it is found that the brake oil color becomes heavier, there is sediment, and there is stratification, it needs to be replaced in time.Because the brake oil has deteriorated at this time, continued use may cause the brake system to be corroded.

2. Brake hose

The pressure of the brake system is relatively high when working, so most of the brake pipes are metal pipes. As long as the vehicle does not support the bottom, these metal pipes will not go wrong.Moreover, even if the bottom support is passed, it is difficult to hurt the brake ducts, because they are all located in a very hidden place under the chassis, and the general bottom support can easily not hurt the brake ducts.

The most important thing to check is the brake hose leading to the wheel.Because the wheels of the car have to jump up and down while driving, the brake pipe leading to the wheels can only be made of rubber, and it is not afraid of bending.However, the rubber will age, and the wheels will beat repeatedly while driving, and the brake hose will be bent repeatedly. Over time, the brake hose may age and crack, thereby affecting brake safety.

Therefore, we should check the brake hose regularly, and if there is aging or cracking, we must replace it in time.

3. Brake discs and brake pads

Many car owners don't know how to check the brake pads. In fact, it's not that you don't know, but that you don't want to spend time.Checking the brake pads of a car is theoretically the same as checking the brake pads of a bicycle.

There is a very thick layer of friction material on the surface of the brake pads, and the friction material and the brake disc are used to produce braking force when braking.With the use of brakes, the friction material on the brake pads is thinned a little bit, and the brake pads need to be replaced when the friction material is almost finished.
