Brake this thing is related to driving safety, so everyone is very concerned about, once the instrument has brake related tips, everyone is unsure, do not dare to open,

The instrument indicates "brake disc wear" what is going on? How much further can we go? Here's a quick chat.

Let's look at why:

Brake pad alarm is generally carried out through the brake pad induction line, with the brake pad wear, once worn to the induction line position, the induction line is worn off or with the brake disc, then the brake pad alarm will be triggered. Therefore, if the instrument indicates "brake pad wear", it means that the engine computer thinks that the brake pad has reached the wear limit and should be replaced.

Of course, this can also be a false positive, such as the brake pad sensing line is disconnected, the relay 87F does not activate the ESP control module, etc. Therefore, it is wise to check the thickness of the brake pads first.

Hint. How far can we go?

If it is really the brake pads wear to the limit, many owners should not dare to drive, if the car is really inconvenient in the field. In fact, wear to the limit, brake pads still have 2-3mm can be used, and the thickness of the new brake pads is generally 10-15mm. Even if the limit value is 2mm, and the thickness of the new film is 15mm, if the brake pad you use 40,000 kilometers, the remaining 2mm can theoretically travel 40000*2/13≈6153 kilometers.

Although the actual car can not according to the theory, but also shows that wear to the limit can also run far.

On the one hand, the brake pads become thinner, and it is easy to be unstable when encountering a sudden brake; On the other hand, the computer will no longer give you hints, if you use it and forget to change it, it is also a dangerous thing.

So, this is actually a choice of the problem, the alarm to run or not to run, depending on your own choice according to the situation at that time. Of course, the alarm is still recommended to change as soon as possible, but it is inconvenient to continue to run, on the road a little more stable, don't always rush on, and then replace as soon as possible after busy.
