Introduction to brake disc replacement: general introduction: check the front brake disc every 60000 kilometers and the rear brake disc every 120000 kilometers. The maintenance cycle specified by different automobile manufacturers is not exactly the same, and the specific replacement cycle shall be subject to the requirements of automobile manufacturers.

1. Listen to the sound: if the brake pad lightly steps on the brake and is accompanied by the sound of "iron rubbing iron" or screaming, the brake pad must be replaced immediately. Because the limit marks on both sides of the brake pad have directly rubbed against the brake disc, it proves that the brake pad has exceeded the limit.

In this case, when replacing the brake pad, cooperate with the inspection of the brake disc. When this sound occurs, the brake disc is often damaged and scratched. At this time, even if the new brake pad is replaced, the sound can not be eliminated. It is recommended to replace the brake disc in time.

2. Usually, whether the brake disc warning light on the instrument panel is on is used as the judgment basis for whether to replace the brake disc. Generally, the indicator is off. When the brake disc fails or is excessively worn, the indicator will be on and off after repair. When the warning light is on, the brake disc has been worn to the limit, and the braking effect has decreased, which greatly affects the driving safety. Therefore, we suggest to regularly check the wear condition of the brake disc to see whether it can be used, rather than just trust the warning light.

3. Look at the thickness: most brake disc products have wear indicators, that is, three small pits will be distributed on the disc surface. Measure the depth of the small pit with a vernier caliper, which is 1.5mm. In other words, the total wear depth of both sides of the brake disc reaches 3mm. When there is quasi wear and complete wear as shown in the figure below, we suggest replacing the brake disc in time. Of course, not all brake discs have wear indicators. We can use our fingers to touch the outer edge of the disc to judge the approximate depth. Generally speaking, if the total wear depth of both sides of the brake disc reaches 3mm, the brake disc should be replaced in time. Brake disc replacement standard: introduction general brake disc rust is actually a normal phenomenon, which has no inevitable connection with quality. At present, the brake discs of most household cars are made of cast iron, without rust prevention treatment like the body surface, and are exposed to the sun and rain for a long time. After parking for a long time, it is easy to generate some rust on the surface. Even if the new car in the 4S store is parked outdoors for a long time, this will happen. The rusty brake disc will have a certain impact on the brake system, but there is no need to make a big fight. If the problem is not serious, the owner can deal with it by himself. As for when to replace the brake disc, it depends on many factors. Generally speaking, the service life of the brake disc is much longer. As long as there is no abnormal noise and jitter when braking, it is not a dream to use 100000 kilometers. There are even and smooth marks on the surface of the normal brake disc. Sometimes there is a large area of rust on the brake disc after rain, which is also a normal phenomenon. But if the brake is abnormal and the new brake pad is not solved, you have to check the brake disc. It is not worn out and can be "repaired and renovated". This is a fine technical work. If it is not repaired well, it can only aggravate the shaking. If the wear is too large, it has to "change the plate"
