But just at this time, the brake system is not sensitive, and the consequences are really unimaginable. The safety of second-hand car maintenance should be put in the first place. Adjustment of automobile brake clearance; adjustment of automobile clutch; replacement of automobile brake discs and pads; maintenance of automobile shock absorption equipment, maintenance or replacement of automobile tires; inspection of automobile circuit oil circuit system; adjustment of automobile light signal, etc.

3. Maintain the fuel system

Under normal circumstances, the car needs to be cleaned and maintained once every 10,000-15,000 kilometers. When you find that the engine is shaking, lagging, poor acceleration, black smoke, powerlessness, and fuel consumption, clean and maintain it once. Remove the colloid and carbon deposits inside the system, prevent harmful corrosion, avoid and stop the leakage of seals and water tanks, and completely replace the old coolant. Replacing with new engine oil, brake fluid, and automatic gearbox oil can improve the dynamic performance of the car and prolong the service life of components. Generally, second-hand cars that have been used for three or four years need to pay more attention to cleaning or replacing the oil filter and fuel filter.

It is best to replace it as soon as possible. Automotive circuits are mainly divided into low-voltage and high-voltage. Check the interfaces of various components of the low-voltage circuit to see if there is ablation of the wires, poor contact, etc. At the same time, pay attention to the condition of the fuse. The life of the battery is about two years, and the life of the spark plug is about 40,000 kilometers.

After the car owner buys the car, it is best to do four-wheel alignment, tire dynamic balance, and check the tire pressure. If the tires are worn out, a new set of tires should be replaced to ensure driving safety. Some second-hand cars may not have had their tires replaced for three or four years. Although the tires look new or have deep pits, the rubber has already hardened and cannot provide the proper grip and must be replaced.

6. Replace wear parts

For second-hand cars over three years old, the belt is an important part of maintenance. Belt misalignment and breakage can easily cause abnormal combustion of the engine, and at the same time cause serious damage to other components. After a certain number of years of use, uneven wear will cause the clutch plate to slip, reducing the effectiveness of the clutch. When the clutch is found to be abnormal, it is best to try to adjust the clutch plate. If the situation still does not improve, you need to consider replacing it.
