The brake system of a car is most important thing in a car's safety system, so if a problem occurs with car's brake system, owner should not be careless, otherwise a serious accident may occur. When buying a new car, car owners can choose between large or small engine displacement, high or low power, manual or automatic transmission, leather or knitted interior, different configurations of car electronics, etc. high end car. But braking system of car cannot be selected. Of course, braking system of car is adjusted to fully match braking force required by current car. However, after brake system has been used for a period of time, various situations will inevitably occur. When a situation occurs, owner cannot judge it by himself, and it is easy to cause unexpected failures.
1. Abnormal brake noise
A more common brake problem is abnormal brake noise. Many car owners have experienced this problem. Typically, abnormal brake noise occurs when brake is pressed while vehicle is moving, brake system makes a sharp metal friction sound, which often appears after rain. If this happens, it is mainly because brake pads have become thinner, rear plate has worn off brake discs, brake pads are hard (poor quality) and there are foreign objects in brake pads, all of which cause abnormal noise. Therefore, if there is abnormal noise of brakes, check first. There is no problem with thickness of brake pads. Pressing brake several times can alleviate the problem of abnormal noise.
2. Hit brakes
Slam on brakes, many of car's main body will be most because car's ABS is activated when brakes are applied, and brake pedal will bounce at that time, which doesn't happen with normal braking. Of course, in addition to normal phenomena, there are also malfunction phenomena. This situation also occurs when surface of brake disc and brake pads is uneven and steel ring is deformed.
3. Brake deflection
Deceleration deviation is also called deceleration deviation. The phenomenon of braking deviation is that steering wheel of car owner obviously deviates to one side when brake is applied. Such a failure is not very common, and once it occurs, it will lead to a big accident. The main reason for this situation is eccentric brake pad wear or a problem with brake cylinder, so once this has happened, you should immediately go to a repair shop for a check.
4. Brake travel becomes longer
Longer brake travel means brakes are softer, as everyone says. When car brakes, normal stroke is longer than standard stroke. In simple terms, this means that brakes can be applied one foot early and brakes need to be stepped on to start when they become soft effect. This kind of situation is that brake has a long shelf life, air is getting into brake system, brake pads are too worn or there is not enough brake fluid, and there may also be an oil leak.
5. The brakes are especially hard
Many car owners have experienced phenomenon that brakes become stiff. Many drivers have experienced this situation because brake booster system is basically a vacuum booster. When engine is not on vehicle, brake vacuum pump is switched off. not produce a booster. When you press brakes at same time, there is no increase in power, and it feels naturally heavy when you apply brakes, so when car is particularly difficult to apply brakes when car is in car, most likely due to problems with vacuum booster (frequent braking also causes this phenomenon).
When situation described above occurs in a car, owner of car should not be careless or treat it as an accident. When brake light on instrument panel is on, it is best to go to nearest repair shop for a simple inspection in order to avoid unnecessary trouble and accidents.
