The weather is gradually getting warmer, and the spring blooming season is coming. In the process of the temperature rising, I found that there was a squeak when I gently stepped on the brakes, which was very harsh. Although I knew that the metal brake pads would have such a sound, I still could not help it. I decided to replace a pair of ceramic brake pads for my second black. Although the cost is high, but think of the mute effect. Bear with it!
It’s just such a small box. 960 RMB.
With 3C certification, rest assured, excellent workmanship.
When we get to the modification store… Don’t say a word… Open it…
After a while, the master removed the brake disc.
See here someone is going to ask: change the brake pads, why do you remove the brake disc?
Answer: the performance of metal plate is different from that of ceramic piece. When replacing brake pads of different properties, try to make the brake disc work on CD and re-run-in to better match ceramic brake pads and avoid brake jitter.
This is the metal brake pads removed. The master told me that if I hadn’t changed the ceramic pads, he would not have agreed to change the brake pads for me at all, because my metal brake pads run-in very well and the edges are flat.
The next step is to check the piston to see if there is any hidden danger that the piston will not return to its position. Check the results: all OK
Both front wheels of Erhei have been dismantled. The calipers hung alone on the dust board, and there was a feeling that the body had been hollowed out.
Give Erhei a high-altitude version of the photo.
While the master CD, I am not idle to help the master, first take out the ceramic pieces, and then pick up the metal pieces to make full use of the debris time.
After the brake pads are reversed, look at these two wheels. Always trying to do something about it… But what exactly do you do?
Because of the metal brake pads… The wheels are full of die-hard fans! Let’s get a guy to do something.
Clean up one…
Next, the right front wheel… Do it!
It’s clean, too!
The rear spoiler is so handsome. The more you watch it, the more you like it.
The wheels have also been scrubbed, and my own housework has been sorted out. Let’s take a look at the master’s CD-ROM action (). During this period, the master said to me: the light brake disc must wait for the brake disc to cool naturally, and must not be cooled artificially, otherwise the brake disc will basically be useless. But some people say it’s all right… Who on earth is right? Personally, I think: the brake disc is not so delicate, as long as it is not watered in a red state, there is generally no big problem. That’s not right. Please correct me.
The brakes on the right front wheel are over.
After a while, the left front wheel was finished.
Ceramic brake pads, get in the car!
After a while, calipers, brake pads, brake discs are all back in place, happy!
When it was all over, after settling the bill with the master, I took my black car for a few laps in the car city, tried the brakes, then saw that there was no problem, and as soon as I turned the corner, I went to the main road: home.
You think it’s over by this time? I thought it was over, too… But this matter is not over, next please watch the egg section!
After Erhei and I drove 5 kilometers out of Motor City, there was a stunned sound when we hit the brakes. So I immediately turned around and went back to Motor City. After removing the brake pads, I found that there were some partial brakes.
After a series of measures:
1 polishing brake pads.-useless
2 reinstall the brake pads.-useless
3 reinstall the brakes.-useless
4 correcting caliper pistons-useless
5 discharge part of the brake oil-useless
6 replace the original metal brake pads-useful, you read it right, it worked!
But I worked hard to spend more than 1000 yuan to replace ceramic brake pads, how can I give up? Now the problem has been locked in the problem of the left brake pads, so using the BOB&WOW split principle, I resolutely asked the master to switch the left and right brake pads, and then on the road to find a closed road, running circles back and forth, finally confirmed my idea: just changed no sound, opened for a period of time began to appear sound, it seems to be a running-in problem.
Next, I will force manual intervention (be sure to choose a closed road, choose a closed road):
1 turn on the emergency flasher
2 turn on the high beam
3 turn on the front and rear fog lights
4 increase the speed to 100 km / h
Five times hit the brakes to reduce the speed to 30 kilometers per hour.
Repeat 4 minutes, 5 steps, 10 cycles.
The voice of Leng Leng is gone.

In order to be foolproof, I simulated the normal road driving state, driving at a speed of 80 km / h, then tapping on the brakes to slow down, gradually stepping on the brakes, and gradually stepping on the brakes until the vehicle stopped. I tried about 7-8 cycles and verified the problem-solving effect, which was very successful!
The great task has been completed! Go home!
True knowledge comes from practice and rejects all rumors.
The experience of this time is as follows:
Ceramic pieces are more expensive than metal pieces.
Ceramic pieces are quieter than metal pieces, and the squeaking sound is gone.
3 to replace the brake pads of different texture, the brake disc needs to be polished.
4 reel and punch plate generally do not give light, because of waste knife, and refit disk material, the quality is unstable, most places are not willing to take risks.
5 if there is an abnormal noise after changing the brake pads and the brake performance is not affected, do not panic, find a closed road, and carry out the work of opening and running-in the brake pads on the premise of ensuring the safety of yourself and others.
Write at the end: modification is risky, you should pay special attention to safety on the road.
