This is when I went to the 4S store for inspection. They told me that the branch pump was broken and there would be oil leakage in this place. The leakage was a bit serious. Fortunately, this car has a front brake. If it was a moment later, it would be a bit troublesome. I was afraid that I would not have brakes when I was running.
It has been more than five years since Dabao replaced the rear brake pads. My Dabao has traveled 110800 kilometers in five years. When the front brake pads were replaced, they were replaced more than 50,000 kilometers. The rear brake pads have never been replaced because they have been on a business trip and have not been opened. I came back and opened it for one day this time. The next day, I found that there was oil leakage in the rear left brake. I went to the 4S shop to inspect it in the afternoon when I discovered it in the morning and said that the branch pump was broken, but I feel that the probability of this branch pump being broken is very small. Finally, I went to a brother I knew. He was a car repair worker. He told me that the branch pump generally would not break, and the brake pads might be worn out, so he suggested that I should replace the brake pads first. If it was okay, then it was not that the branch pump was broken. He asked me to come and change it the next day. I was really unsure at that time, so I had to replace it first and have a look.
Looking at this place from the inside, it is quite obvious that the oil is seeping out. There is oil on the wheel hub. It is the oil thrown out when I was driving a sports car. I discovered it then, otherwise it will be broken and there will be no brakes
After removing the tire, I saw it clearly. It was really leaking oil. The mechanic said you discovered it early. If you discovered it too late, it would be a bit troublesome. You really have to replace the sub-pump in the end.
There is a photo coming from the back and there is a lot of oil on the back. It seems that it has not been a day or two
The master began to remove the brake pads for me, and then used a special tool to press the brake cylinder back, but he couldn’t press it too hard. He also used the brake pads to push it back.
Look at this brake pad that has traveled more than 110,000 kilometers. The brake pad of this original car is good, but the one bought elsewhere now cannot run so much. At most, it will be easy to replace it after running 60,000 kilometers.
Looking at this thickness, the difference between the new and the old one is really used to the end. Otherwise, how could the branch pump leak?
In order to confirm whether the branch pump was broken, I washed the wheel hub separately. I didn’t see brake fluid after running all afternoon. This means that it was really the brake pads. In this way, I was relieved. I will run for a few more days and have a look. From now on, there is no problem.
