D840 Brake Pads

Brake pad replacement factor

The car is driving on the road and its braking system is very important. The thickness of the new brake pads in the brake system is generally around 16 mm, and the thickness will gradually become thinner as the friction is constantly used. When the thickness of the brake pad is visually observed to be only about 1/3 of the original thickness, the owner must increase the self-test frequency and be ready to replace it at any time.

The replacement of the brake pads depends on many factors, such as the quality of the brake pads, driving habits, time of use and road conditions. When the exercise is more than 50,000 kilometers, the brake pads need to be checked frequently. However, if you hear the friction from your wheel, no matter how much mileage you have, you should replace the brake pads. Because the alarms on both sides of the brake pads have directly rubbed the brake discs, it proves that the brake pads have exceeded the limit of use. In addition, if the brakes feel very difficult, it may be that the brake pads have basically lost the braking force, and must be replaced at this time, otherwise it will cause serious accidents.

How to maintain the brake pads

Cars need to maintain a good state as we do, so we usually need to pay attention to the observation and maintenance of the details. Only when the hidden dangers are detected and early maintenance can the vehicles be maintained in a good working condition. There are many places where vehicles need to be maintained.

In the brake system of the car, the brake pads are very important parts. To some extent, the brake pads and brake discs determine the braking effect. Therefore, we need to check the brake pads regularly, once the brake pads are found to reach the critical point. To the extent, it needs to be replaced in time.

The oil of the car also plays an important role. The engine oil is needed in many places of the car. Its main function is to protect the parts and make them run smoother and longer. At present, the oil on the market uses SAE and other grades to identify the viscosity. The smaller the front number, the thinner the oil, the better the low temperature fluidity, the better the cold start capability, and can be used in a lower temperature environment.

How often does the brake pad change?

First of all, it is obvious to see the warning lights. If there is a brake warning light on your dashboard, when it lights up, say that you want to change the brakes. However, the shortcoming of this method is that not all cars have brake warning lights, and the warning lights are not the same; some are based on the thickness of the induction brake pads, and some are when the brake pads are finished and the brake oil is also fast. The warning light will only be illuminated when it is exhausted; the latter situation is even more dangerous. Therefore, the warning light can only be used as a reference and cannot be completely relied upon.

Second, check the height position of the brake fluid. We open the brake fluid pot to see where the brake fluid is located; normal is between the two scales, over or under will affect the braking effect. There is also the sense of strength when braking. If the brake pads and other components in the brake system are quickly exhausted, the owner will obviously feel that he can't stop the car according to the usual strength when he is stepping on the brakes. It is necessary to check which parts to replace. Another way is to take it down and see if the thickness of the brake pads is enough. Under normal circumstances, a new brake pad has a thickness of about 1.5cm. When the wear exceeds a certain range, the brake pad should be replaced. Brake discs generally do not need to be replaced frequently, but if rust, wear, etc. are very serious, they must be replaced.

The purpose of the self-checking brake system is to allow everyone to pay more attention to the braking effect of the vehicle. It also has an estimate of how often the brake pads of the vehicle are changed. After all, braking in a dangerous moment is a safe happiness. Friendship reminds us that when we choose which brake pad to use, we must pay special attention to whether it comes from regular manufacturers and when it is safe. Nothing is safe, don't neglect safety because it saves money.
