Regular car maintenance is essential, but most car owners don't know how often to maintain their cars. Take the brake disc for example. It plays an important role in braking the car, but many owners either neglect maintenance or save money to wait for the next maintenance, and often put off the car, which can cause a series of problems. For the brake disc need how many kilometers to change the problem, a maintenance master gave advice, as the maintenance master said: do not want to save more than this number. How many kilometers does it take to change the brake disc?

As the mileage increases, the brake pads and discs are used more and more, and therefore wear out. If the number of times of braking, the thickness of the brake pad and brake disc will be significantly thinner, not only will extend the braking time, but also will extend the braking effect, resulting in the safety of the car manual certain threats. Therefore, after a certain mileage, the owner needs to change the brake disc.

First of all, for the brake disc, its volume is relatively small, when the brake, it will be more concentrated wear and tear, so it will be relatively short time to use, the car about 30, 40 thousand kilometers after the need to replace the brake pad. The brake pads are relatively bulky and less easily worn out, but they also need to be replaced after the brakes have been replaced twice, after the car has travelled about 80,000 kilometres.

In addition, when replacing the brake pad and brake disc, the car owner can judge whether the car should be replaced by these parts according to the car's driving distance, and the car owner can also judge the quality of the brake system according to the sound of the brake. If the car brake pads wear seriously, in the process of braking, it is very easy to produce the sound of metal friction with metal, at this time the owner needs to take the initiative to check the car's brake disc or brake pads whether there is serious wear, so as to replace.

In addition, some owners also found that the brake disc "rusted" situation, at this time need to be replaced? This should be considered separately. For the brake disc slightly rusty case, the owner can step on the brake more, as long as the rust is worn down, the brake disc can be "as bright as new"; However, if the brake disc rusts badly, the owner will need to have the mechanic take it apart for rust removal.

Thus it can be seen that in order to avoid serious wear and tear on the brake disc, the owner should remember the number "80,000 km", for the maintenance of the brake system on the problem, even if the owner again want to save money also do not exceed this number.
