With the popularity of private cars in China, many car owners and friends own their own cars, but if they buy a car, as long as it is not unlimited use, it will definitely be no problem to drive it for 10 or 8 years. After all, the money to buy a car is not a small amount. Many people still hope that their car can be used for a few more years, so car owners love and maintain it. But for the maintenance of the car, it is not just to change the oil. It can be said that if these 4 parts on the car are not replaced, it is a waste of maintenance.
The first thing to replace is the brake cylinder.
This part can be said to be often overlooked, because of its location, the things it comes into contact with the most are mud and water, which makes this place always dirty. But also because of these things, this part is easy to rust. If this part is rusted, the wheels of the car will be locked all the time, the braking ability will be reduced, and the fuel consumption of the car will also increase significantly. So the maintenance of this part is also very important. Generally speaking, it is better to replace the car after driving 20,000 kilometers.
The second is the ball cage, the ball cage is also called constant velocity universal joint, which is an important component of the car transmission system.
The function of the ball cage cover is to prevent dust from entering the ball cage and prevent the butter in the ball cage from flowing out, so it is also a relatively critical existence. Moreover, it is necessary to use high-temperature-resistant grease in the ball cage. If other substitutes are used, it will also cause a more obvious sense of poking to the car. In severe cases, it may even lead to car breakdowns and accidents.
The third one I believe many people are familiar with is brake fluid.
This is the oil needed by the brake system. I believe everyone understands the importance without saying too much. If there is a problem with the brake, it will not be a small problem, so its replacement is also very important, and I believe no one dares to ignore its replacement. Because the temperature of the brake system will also increase during the long-term use of the car, generally there will be air resistance to the brake pipeline, which will cause a decrease in brake sensitivity. For safer driving, it must be replaced in time.
The fourth is the spark plug.
This part also plays a vital role in the ignition process of the gasoline engine. So consumption is also more serious. These parts have a service life, and generally need to be replaced when the car travels between 20,000 kilometers and 150,000 kilometers. The specific replacement time still depends on its material. The general material needs to be replaced at 50,000 kilometers, but the better material can be replaced even at 100,000 kilometers.
