Everyone must know that cars need maintenance when driving a certain mileage, whether you are a private car priced at 100000 or a top luxury car priced at millions, you cannot escape this. Many novice drivers who go for maintenance simply follow the instructions of the staff and do not know how to make their own judgments and choose maintenance items. Most of the time, these maintenance items involve changing various types of oil, coolant, glass water, and so on. Over time, the areas that were supposed to be maintained were overlooked, and ultimately it was only after the car malfunctioned that it was discovered that the problem was due to untimely maintenance. Today, let me talk to you about car maintenance.

1. Suspension liner

Many people are confused when they see this part, and may not even know what it looks like. The position of the suspension liner is at the connection of various parts on the car suspension. Car suspension is like a human joint, a car without suspension cannot turn. The parts on the suspension are all metal structures, and direct contact with metal parts will definitely cause wear and tear, and strange noises will be made when the parts rub. The suspension liner is a rubber strip that protects the connection between metal parts. Of course, in addition to its protective effect, it can also reduce noise. Rubber products tend to age and corrode, so when a car reaches a certain mileage, the suspension liner needs to be replaced.

2. Brake oil

Brake oil is also considered a type of car oil, but many people think that changing the oil is just changing the oil in the engine, so they ignore brake oil. The function of brake fluid cannot be ignored. Many people say that brake fluid is used to reduce the wear between brake pads and brake discs, but the most important thing is that if a car wants to brake, it must rely on the brake master cylinder and brake master cylinder to push the brake pads. At this point, the role of brake fluid is to transmit the effect, and it usually takes about three years for us to replace the brake fluid once. If not replaced for a long time, be careful not to scrap the brakes.

3. Spark plug

As long as you are a gasoline engine car, you cannot do without spark plugs, which are an important component of the engine. What is the specific function? Everyone knows that engines rely on fuel, air, and sparks for operation, and the spark plug is the key to igniting fuel when the piston is pushed to its highest point. If a car can run without a spark plug, it can only indicate that it is a new energy vehicle. Spark plugs are also prone to aging and carbon buildup, so they should be cleaned in a timely manner.

The above points are all things that we need to pay special attention to in car maintenance. For example, the suspension liner is usually discovered by the car owner themselves and then requested to be replaced. The maintenance does not include the suspension liner in the maintenance items.
