If you don't change these four parts, it's a waste of money to do car maintenance!

It's easier to buy a car than to maintain it. Proper car maintenance will also prolong the service life of the car and ensure our safety when driving. Most people choose to go to the 4S store to change the engine oil because they are not professional. However, car maintenance is more than just changing the engine oil.

Don't ignore the four parts

If these four car parts are not replaced, then the car maintenance will be done in vain. First, the car spark plug, which is an extremely important part of the gasoline engine ignition system, if the car spark plug is not maintained, there is too much carbon deposition or too much precipitation, the spark plug gap is increased, and the ignition energy is insufficient, it will cause the car to start difficult, so timely It is also necessary to replace the spark plug or check it more often.

The abnormal noise of the engine is that it is broken

Second, the car constant velocity universal joint, to put it bluntly, is the rubber sleeve to protect the ball cage, which can prevent dust from entering and sealing. If your car usually has a strong sense of frustration or the car engine makes a strange noise, it is likely that the ball cage is leaking oil. If the situation is more serious, there will be traffic accidents. Therefore, this part should also be maintained according to the maintenance week If there is a problem, replace it in time.

The brake oil must be replaced in time

Third, the special oil for automobile brake. The brake oil is actually used as an auxiliary for hydraulic braking. However, because it is easy to absorb water, there will be a lot of water in the brake oil over a long period of time, which will reduce the brake sensitivity of the car. In order to drive more safely, it must be replaced in time.

Metal parts rust easily

Fourth, the brake wheel cylinder is easy to be ignored because of its location. The most common thing that causes it to touch is soil and water, which makes this place always dirty. After all, it is made of metal. After all, rust will appear after a long time. In this way, the brake performance of the car will definitely decline. If we neglect it during the maintenance of the car, if we do not pay attention to it, we will not pay attention to it It will affect our driving safety.

There is no trivial matter in safety, and the maintenance of the car can not be ignored.
