Many of you have no idea about the accessories for your car. When exactly do you need to change them? When do you need to maintain them? These questions have always troubled us. Here come the benefits, today we'll give you a brief introduction!
Tyres
How long do tyres last? I am surrounded by car owners and friends generally believe that it is 5-6 years, and some friends even think that the wheels do not need to be replaced even if they are not worn out of wire, gosh! In fact, the lifespan of tyres is closely related to many factors. For example, climate, road, driving style, installation, maintenance and repair, etc.
In terms of international regulations, tyres must be replaced when they are worn to a tread depth of 1.6 mm if they are used properly. Almost all tyres are marked with a tread depth of 1.6 mm. If used normally, the average tyre has a mileage of around 50,000-100,000 kilometres. However, it is important to remember that tyres are valid for 5 years after leaving the factory. As rubber has an ageing period, it is advisable to replace them, regardless of whether the mileage reaches 100,000 km, when they reach the 5-year period after leaving the factory.
Brake pads
The service life of brake pads is usually determined by the frequency of braking and road conditions. As a rule, brake pads need to be replaced when driving around 50,000-80,000 km, if the degree of wear is calculated to a limit of one third.
Generally speaking, under mixed driving conditions (half road, half city), the brake pads on the front wheels should last 60,000-70,000 kilometres. The rear brake pads should last for more than 100,000 km. Of course, this is not absolute, it is just a rough estimate. The front brake pads wear out faster because when braking, the car's centre of gravity is tilted forward and the front brake has to withstand more force than the rear brake.
Therefore, the front brake discs are generally larger than the rear brake pads. When you have changed the brake pads, the braking effect will not be as good as before and the brakes will feel softer. In addition, you need to break in your car for 200km to achieve the best braking effect. You should drive carefully with the newly replaced brake pads and pay attention not to follow the car too closely.
Brake fluid
The brake fluid has a service life of 60,000 km or 3 years. It is worth mentioning that it is best to change the brake fluid on time, otherwise it will deteriorate and cause air resistance, resulting in brake failure.
The normal brake fluid replacement interval is three years. Although brake fluid does not have much effect on the surface after a long period of use, problems are likely to arise when the vehicle is under emergency braking or when driving on downhill roads for a long period of time. Braking systems can cause brake fluid temperatures to rise rapidly during prolonged or emergency braking.
The brake fluid itself has strong water absorption characteristics, it will absorb moisture from the surrounding air, such as car washing, humid air, etc., there will be water infiltration, the accumulation of moisture into the brake fluid over time will directly cause the brake fluid boiling point to drop, resulting in a decrease in braking power. It will also lead to air resistance in the brake lines, (search cheworld for more car knowledge) thus affecting the performance of the brakes.
In addition, water will also corrode the brake lines and cause damage to the internal valves of the anti-lock brake (abs) hydraulic assembly, which will seriously affect the transmission response of the brakes. In addition, the brake fluid will also cause wear and tear on the brake bowl and piston in the brake pump over time, resulting in cloudy brake fluid.
The quality of the brake fluid is very important and more attention should be paid when choosing brake fluid. If it is substandard or of average quality, it will corrode the plugs in the brake pump and have an effect on the braking effect.
Battery
Many vehicles now use maintenance-free batteries, which have a theoretical life of 2 years. The 3 year life of a water filled battery is subject to the prerequisite of keeping the water in the battery within the standard range, if there is a shortage of water this will shorten the life. Maintenance-free and water-added batteries can last up to 50% longer if they are recharged every 5000 km with a special recharger. When driving at night, as soon as the lights go dark when you put it into neutral or at idle, it is a sign that the battery is about to be replaced. However, some batteries currently do not last as long as their theoretical life expectancy, depending on the model.
Spark plugs
The service life of spark plugs is 30,000 kilometres for normal models, 50,000 kilometres for platinum models and 70,000 kilometres for iridium models.
Car maintenance is very troublesome, when the car travels to a certain number of kilometres, the spark plug will produce carbon electrode gap will also increase, carbon will make the engine fuel consumption increase, spark plug gap increase will cause starting difficulties. Therefore, often check the maintenance of spark plugs, can extend the life of the engine.
To do maintenance, first of all, you should regularly clean the air filter to avoid dust with the mixture into the combustion, which can prevent the spark plug by corrosion. Secondly, you can also remove the spark plugs yourself, clean the ignition head of dirt, carbon. However, special attention should be paid to the spark plugs when disassembling and installing them, pay attention to the spark plugs in and out, pay attention not to let the dust into the cylinder, should be cleaned around the spark plugs in advance when removing them.
If there is oil in the cylinder, the piston rings or other parts should also be replaced in time to avoid the accumulation of carbon in the spark plug causing a short circuit in the electrode. In addition, the fuel oil is also closely related to the life of the spark plug, so you must pay attention when refuelling, should not be greedy for cheap to add the quality of the problematic oil, or regret too late.
