In the daily use of the car, most car owners will only open and not repair, the phenomenon that the owner is not a professional maintenance personnel is affirmative, but as a car owner still have to learn from the car's subtle phenomena to determine the common signs of failure, This is helpful for early detection of the hidden dangers of the car and early maintenance. In this article, the author will teach you from four aspects of safety to determine where the hidden troubles exist.

When it comes to judging the hidden dangers of the faults from the nuances, the author believes that the first thing to think about is the throttle, brake, clutch, and steering wheel. So how much do you know about them in these four cases? Can you find that the car has hidden dangers from these four places?
    
First of all, let's get to know the throttle: the throttle is a power control device of the car. Although it is called the throttle, it is not directly controlling the fuel intake of the car. The fuel intake of the car is controlled by the opening of the throttle. The opening of the throttle valve directly affects the calculation of the amount of fuel injected by the engine computer, thereby controlling the starting, accelerating, overtaking, and oil-cutting actions of the car. The above are some of the principles of the things, if the reader is difficult to understand, you can skip it, just remember the problem phenomenon mentioned below and the fault it reflects.

First, if you feel the throttle characteristics and issue the card when you step on the accelerator, the general reason is that the throttle is dirty or the throttle cable is not lubricated. You need to clean and lubricate the car.

Second, when you feel fuel, if you feel that the throttle is not responding quickly or you feel that the engine is not strong, then you should go to the service station to check the spark plug, fuel injector and throttle to see if you need to replace the spark plug or clean the throttle and spray. The nozzle is gone.

Then you should know the brakes: the brakes are a key part of the car; its working condition is directly related to the safety of our car and the human body, so don't underestimate it. Then, when we usually brake on the brakes, how can we find out the problems as soon as possible to eliminate hidden dangers?

    
First, when the brake pedal is turned off, the brake pedal must have sufficient hardness and height, and the brake pedal should not have any feeling of sliding down when it is pressed hard to keep still. The feeling of the car pedal sliding should be checked to the repair station in time to see if there is any oil leakage in the brake system.

Second, after starting the car, pressing the brake pedal should not have a foot in the end, otherwise the brake system should be repaired immediately.

Third, after starting the car, step on the brakes. If the first foot is low, after stepping on a few feet, it will be normal. After releasing the brake pedal for a few minutes, then stepping on the first foot and then stepping on the foot will return to normal. When there is air inside the brake system pipeline, you should go to the repair station to deflate the brake system.

Fourth, when you step on the brakes, if you hear the brakes with iron iron screams, you should check to see if the brake pads are thin and need to be replaced. If it is not thin, there is a possibility that the hard spots on the brake pads are ground to the brake discs. Produced; (If it is a slight scream, you don't have to care; it will be better after a while; but if it is a particularly large scream, it should be handled or replaced in time, otherwise it will cause the brake disc to grind out the ditch for a long time. Come).

Fifth, the brake oil should be checked from time to time. If it is too dirty, it should be replaced in time. Two or five thousand kilometers is also a term for replacing the brake oil. It is best not to exceed it.
