How To Judge The Quality Of Auto Cable?

In the daily use of the car, most car owners will only drive and not repair it. The phenomenon that the car owner is not a professional maintenance person is affirmative, but as a car owner, we still have to learn to judge the common trouble signs from some subtle phenomena of the car. This is helpful for early detection of hidden troubles in vehicles and early maintenance.

Speaking of judging from the subtleties of the hidden troubles, the author believes that the first things that should be thought of are the accelerator, brake, clutch, and steering wheel. So how much do you know about them among these four? Can you find out that there are hidden dangers in the car from these four places?

First of all, let's get to know 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. , The opening degree of the throttle valve directly affects the calculation of the fuel injection amount by the engine computer, thereby controlling a series of actions of the car, such as starting, accelerating, overtaking, and cutting off the fuel.

The above are some of the principles, if the reader is difficult to understand, you can ignore it, as long as you remember the problem phenomenon mentioned below and the malfunction it reflects.

First, if you feel that the accelerator is very astringent when you step on the accelerator while driving, the general reason is that the throttle is dirty or the throttle cable lacks lubrication. At this time, you need to clean and lubricate the car;

Second, when refueling, if you feel that the throttle is not responding quickly or the engine is boring, then you should go to the repair station to check the spark plug, fuel injector and throttle valve to see if you need to replace the spark plug or clean the throttle valve and sprayer. Glib.

The next thing that should be realized is the brake: the brake is a key part of the car; its working condition is directly related to the safety of our vehicles and people, and it must not be underestimated. So, when we usually step on the brakes, how can we find out the problems as early as possible and eliminate hidden dangers?

First, when the brake pedal is turned off, the brake pedal must have sufficient hardness and height, and when it is stepped on to keep it still, the brake pedal should not have any sensation of sliding down. If the foot feels sliding with the brake pedal, you should go to the repair station to check in time to see if there is an oil leak in the brake system.

Second, after starting the vehicle, if you press the brake pedal hard, there should be no one foot to the bottom. Otherwise, the brake system should be checked and repaired immediately.

Third, step on the brakes after starting the vehicle. If the first foot is very low, it will be normal, and after a few minutes after releasing the brake pedal, it will return to normal if the first foot is very low. It means that there is air in the pipeline of your brake system, and you should go to the repair station to bleed the brake system in time.

Fourth, if you hear the scream of iron grinding on the brake when you step on the brake, check in time 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 have worn the brake discs. Produced; (If it is a slight scream, you don’t need to care; it will be fine after a while; but if it is a particularly loud scream, you should deal with it in time or replace the brake pads, otherwise it will cause the brake disc to grind out grooves for a long time. Come).

Fifth, the brake fluid should be checked from time to time. If it is too dirty, it should be replaced in time. Two years or 50,000 kilometers is also a time limit for the replacement of brake fluid, and it is best not to exceed it.

Next comes the clutch: clutch usually rarely causes problems. However, there are usually several issues to pay attention to: if it is a pull-wire clutch, pay attention to whether there is a jam when stepping on the clutch pedal. If there is, check whether the pull cable is worn or napped and replace it in time; if it is a hydraulic clutch , You must pay attention to whether the pedal feels that it cannot be cut when gear is in gear. If there is, check whether the clutch hydraulic system has oil leakage. Another is to pay attention to whether the clutch is getting higher and higher and slipping. At this time, it is necessary to check whether the clutch disc should be replaced.

The last thing I want to talk about is the steering wheel: the steering wheel is an important control component in the car, it can remind us a lot of things.

First, if the steering wheel trembles only when the vehicle speed is between 80 and 90 kilometers, this signal is generally to remind you that it is time to balance the tires of the vehicle;

Second, the steering becomes heavy when turning; this phenomenon is likely to be caused by the tightness of the tie rod end of the steering system or the steering bearing or the lack of oil jamming, and another possibility is caused by insufficient tire air pressure. It should be timely Overhaul

Third, the direction is difficult to control; when driving or stepping on the brakes, the direction will deviate to one side. At this time, there may be a loose part of the chassis suspension system or a problem with the inclination of the front wheels; or a bearing on one side Or there is a problem with the shaft head;

Fourth, the steering gear is not properly returned or the angle of turning the wheels on both sides is inconsistent; at this time, it is necessary to check whether the four-wheel alignment of the vehicle is correct;

Fifth, when you turn the direction, you hear a hum from the steering gear, especially when refueling. At this time, it may be caused by the lack of oil inside the power steering gear or the wear and tear of the booster pump; check the power steering at this time. Whether the system leaks oil and deal with it in time to avoid greater losses.

Generally speaking, in the process of using the car, car owners still need to pay more attention to some abnormal phenomena in details, because these phenomena may be the precursors of some major failures. Only by discovering the problems in time and solving them as soon as possible can the safe driving be effectively guaranteed.
