Many riders actually do not know, after the car changed the new brake pads, the brake pads need to be run in, why some owners changed the brake pads appeared abnormal brake sound, because the brake pads did not run in, let's understand some knowledge of brake pads run in.
Question 1: Why do newly bought brake pads need to be broken in?
It doesn't match the brake disc we used earlier
Let me make an example, that is, your new brake pads are replaced, the brake pad surface is relatively flat, the brake disc because the front is used, we generally have two brake pads with a brake disc.
When the brake disc is used, its contact surface is not peaceful because of the use and wear in front of it. The new brake pads and the old brake discs, when they're next to each other, it's very much like when you put a bar of soap on the washboard and rub it back and forth. Easy to cause damage to the new brake pads
Imagine, first of all, its contact area is relatively small, and your braking force will be worse than the original.
Second, it causes a more rapid and violent abrasion, and the washboard rubs the soap off, like a potato.
Question 2: What should we do with the new brake pads? What are the brake pad running-in methods
What are we going to do with the new brake pads? If you don't bother, it makes sense to use this method.
Field grinding
The car goes like 90 miles an hour, and then the brakes gently tiptoe over there, just a little bit, when you feel the brake pads touching the brake disc, just gently tiptoe over there. Just let it go and grind over there. So how much time is it going to take? It's like going from 90 miles an hour to 10, 20 miles an hour. You don't need to be very strict to stare at the stopwatch over there, almost slow down. Repeat this method two to four times and it is basically OK.
More uniform than normal braking
Then some friends may think, you are so grinding, that and my normal use of the brake has anything to do with it? We're going to do this lightly, it's going to be relatively even, and then the effect is going to be better.
If you have just put on new brake pads and a sudden brake goes down, it may really be the washboard that has scraped off a large piece of soap, and you are not prone to this situation after grinding it flat.
But many friends often do not have this kind of road conditions, or technology, or conditions, or time to do this thing, to give you a simple solution.
Mechanic grinding (brake pads run in fastest)
When the new brake pads are replaced, tell your repairman to help me polish it, some of the masters needless to say will polish, in order to prevent the brake pads from ringing, after all, there is no working time to re-open. In fact, grinding will not affect the life of the brake pads, grinding is just grinding the corners, the brake pads are mainly produced by the middle part of the brake.
