Why brake disc wear often occurs after changing pads

When, after the usual replacement of brake pads with new ones, severe wear of the brake discs suddenly begins, the driver is surprised. After all, there was not even a hint of such a problem before. Ukr.Media informs about how something like this can happen, and what to do in such a case.

Usually, when buying brake pads, drivers focus on what the seller advises, especially without delving into the details. Often limited to standard questions, such as whether the spare part is suitable for a specific car brand. Meanwhile, such an approach threatens problems, because the spare parts market is filled with both unknown Chinese products and outright fakes. After all, ordinary, at first glance, brake pads can bring a lot of problems.

Let's start with the cheapest products, which our customers pay more and more attention to. In the production of available spare parts, it is necessary that the pad contains a lot of abrasives so that the product has a high coefficient of friction. After all, the effectiveness of braking depends on this. As a result, such pads not only make a lot of noise when the car slows down, but also actively wear out the discs. The latter quickly become unusable, and now their replacement will be expensive.

And if we talk about outright fakes, where the abrasives are too hard, then many small grooves appear on the discs over time. Approximately such as if a stone got between the disk and the pad. These furrows worsen braking and force the discs to be replaced.

It is also interesting that the composition of high-quality brake pads includes three dozen different materials, including lubricant! Lubricating components of pads are necessary because they make their operation quieter and protect against excessive wear. If all the components are selected properly, then such a pad not only effectively brakes, but also perfectly dissipates heat, and does not crumble under high loads.

Cheap pads or low-grade products cannot boast of such qualities. This puts a load on both the pads and the discs. The pads may even burst into flames with several intensive brakings. This can lead to local heating of the disc. It can lead to this, which affects the effectiveness of the deceleration.
