However, there are many configurations on the car, if a screw in the key part is loose, it may affect the use of the car, so the owner will regularly send the car to do maintenance in order to use the car longer and the safety of the car. But is car maintenance about changing oil? The car repairman said that the following 4 parts are not replaced, and the maintenance money will be paid in vain!
The first part is the brake pump. This part is located in the chassis, so many owners will ignore it when they use it, but in the process of using the car, this part is easy to contact with muddy water and small stones, and it is easy to rust and age. At this time, the wheels of the car will be locked, and the braking ability will drop a lot. Therefore, this part should be replaced in time during maintenance.
The second part is the ball cage cover. This part is also very important for the car, it is mainly to prevent the grease of the car from flowing out, while preventing some dust stains from outside the car from entering the car, which can ensure the normal operation and service life of the vehicle.
If it is aging and damaged, the ball cage inside is easy to damage the car maintenance needs to spend a lot of money, so when maintaining, we must pay attention to the situation of this part, we should change it, and do not let the maintenance money be paid in vain.
The third component is the brake oil, many people feel that even if the oil is changed, even if it is maintained, in fact, this is not right, the brake oil also needs to be replaced, it has a strong water absorption, the use of a long time will have a lot of moisture, will affect the safety of the brake, so also pay attention.
The fourth component is the spark plug. The volume of this part is relatively small, but its role is relatively large, if it has a problem, the car will appear abnormal ignition and start difficulties, and even in use will cause the car to vibrate abnormally, in the maintenance of the time to pay attention to the situation of this part. Although the time of replacement of spark plugs of different materials is different, this part is easily affected by carbon deposits, and if there is more carbon deposition in the car, its work is prone to abnormalities and damage.
Moreover, cars with more carbon deposits in the car are prone to power reduction, fuel consumption increase, and increased noise, and if the engine is seriously accumulated, it may be scrapped in advance. Therefore, if the power and fuel consumption of the car are abnormal, it is necessary to pay attention to the removal of carbon deposits.
