In the daily use of cars, most car owners only know how to drive and cannot repair, and it is certain that car owners are not professional maintenance personnel. However, as car owners, it is still necessary to learn to judge common fault symptoms from some subtle phenomena of the car. This is helpful for early detection of potential faults in the vehicle and early maintenance. The author of this article will teach you how to determine the hidden dangers of faults from the subtle aspects related to safety?

When it comes to judging the hidden dangers of faults from subtle aspects, the author believes that the first thing to think of is the throttle, brake, clutch, and steering wheel. So how much do you know about these four things? Can we find that the car already has hidden dangers from these four places?

First of all, let's know about the throttle: as a power control device of the car, the throttle is called the throttle, but it does not directly control the fuel intake of the car. The fuel intake of the car is controlled by the opening of the throttle, which directly affects the calculation of fuel injection by the engine computer, thus controlling a series of actions such as starting, accelerating, overtaking and fuel cut-off of the car.

The above are some principles that readers can skip if they find it difficult to understand. Just remember the problem phenomena mentioned below and the faults it reflects.

First, customized transparent car lampshade - if you feel that the accelerator is too tight when you step on the accelerator while driving, the general reason is that the throttle valve is dirty or the accelerator cable lacks lubrication. At this time, you need to clean and lubricate the car;

Second, the transparent car lampshade is customized. When refueling, if you find that the accelerator does not respond as quickly as usual or the engine does not feel strong, you should go to the maintenance station to check the spark plug, fuel injection nozzle and throttle to see if you need to replace the spark plug or clean the throttle and fuel injection nozzle.

Next, it should be recognized that the brake is a key part of the car; The good or bad working condition of it directly affects the safety of our vehicles and people, and we must not underestimate it. So, how can we detect problems and eliminate hidden dangers as soon as possible when we step on the brakes on a regular basis?

First, customized transparent car lampshade - when stepping on the brake pedal with the engine off, the brake pedal must have enough hardness and height, and the brake pedal should not have any sense of slipping down when it is firmly stepped on and kept still. If there is a feeling of the foot slipping with the brake pedal, you should go to the repair station in a timely manner to check if there is any oil leakage in the brake system.

Second, customized transparent car lampshade - there should be no foot to the bottom when you step on the brake pedal after starting the vehicle, or the brake system should be repaired immediately.

Third, customized transparent car lampshade - start the car and step on the brake. If the first foot is too low, it will be normal after stepping on a few feet. Release the brake pedal for a few minutes and step on it again. The first foot will be normal after stepping on a few feet too low; At this point, it indicates that there is air inside the brake system pipeline. You should go to the maintenance station in a timely manner to bleed the brake system.

Fourthly, if you hear a squeal of iron grinding on the brake when you step on it, you should check in a timely manner to see if the brake pads are thin and need to be replaced; If it is not thin, there is another possibility that the hard spots on the brake pads may have worn onto the brake discs, resulting in the formation of the hard spots; (If it is a slight scream, you don't need to worry; it will be fine after a while; but if it is a particularly loud scream, it should be dealt with or the brake pads should be replaced in a timely manner, otherwise it will cause the brake discs to wear out grooves over a long period of time).

Fifth, brake oil should be checked periodically. If it is too dirty, it should be replaced in a timely manner. Two years or 50000 kilometers is also a deadline for replacing brake oil, and it is best not to exceed it.

Next up is the clutch: the clutch generally has few problems. But there are also several issues to pay attention to in daily life: if it is a cable type clutch, it is necessary to pay attention to whether there is any jamming phenomenon when stepping on the clutch pedal. If there is any, it is necessary to check the cable for wear and burrs and replace it in a timely manner; If it is a hydraulic clutch, pay attention to whether there is a feeling that the pedal cannot be cut when shifting. If there is, check the clutch hydraulic system for oil leakage. Another thing is to pay attention to whether the clutch is stepping higher and there is slipping. At this point, it is necessary to check whether the clutch plate should be replaced.

The last thing to say is the steering wheel: as an important control component in the car, the steering wheel can remind us of many things.

First, customized transparent car lampshade - if the steering wheel shakes only when the vehicle speed is maintained at 80 to 90 km, this signal is generally to remind you that it is time to do dynamic balancing of vehicle tires;

Second, the transparent car lampshade is customized - it turns heavy when turning; This phenomenon is likely caused by the tight fitting of the steering system's pull rod ball joint or steering bearing, or a lack of oil or jamming. Another possibility is that the tire pressure is insufficient and should be repaired in a timely manner;

Third, the transparent car lampshade is customized - the direction is difficult to control; When driving or applying the brake, the direction may deviate to one side, which may be due to looseness in a certain part of the chassis suspension system or issues with the inclination of the front wheels; Or there is a problem with one side of the bearing or shaft head;

Fourth, the customized transparent car lampshade - the steering gear does not return well or the angle of turning wheels to both sides is inconsistent; At this point, it is necessary to focus on checking whether the vehicle's four wheel alignment is correct;

Fifth, customized transparent car lampshade - when turning the direction, you can hear the hum of the steering gear, especially when refueling, which may be caused by the lack of oil in the power steering gear or the wear of the power pump; At this point, it is necessary to check the power steering system for oil leakage and promptly handle it to avoid causing greater losses.

Overall, car owners should pay more attention to some abnormal details during the use of their beloved car, as these phenomena may be the precursor to some major malfunctions. Only by promptly identifying and resolving problems can safe driving be effectively guaranteed.
