In most cases, squeaking when braking is the cause of wear or contamination of vehicle parts. We identify the cause of the squeak and deal with it correctly.
The annoying squeak of the brakes can infuriate even a very balanced driver. Moreover, if you have to move in a city with its traffic jams, traffic lights and, as a result, the need for frequent braking.
It should be emphasized right away that extraneous noise in the brake system does not always indicate its poor performance. Indeed, although manufacturers try to minimize them by applying anti-noise mastic, installing anti-squeak plates, adding various kinds of special components to the friction mixture, their main task is to ensure a stable coefficient of friction, which ensures traffic safety. Resonant phenomena in the pad / disc friction pair are inevitable, but, of course, it is better that they are quieter and do not indicate poor brake performance. But, in any case, the reasons for the appearance of a squeak, whistle and other extraneous sounds need to be understood.
Squeak when braking: causes and elimination
1. Failed quality
One of the main reasons for the appearance of a squeak during braking is the poor quality of the pads or the mismatch of standards between them and the disc (it is better that they are from the same manufacturer). If you bought them at a low price, somewhere “on the occasion,” it's time for reckoning. In addition to troubles with sounds, they can also damage the brake disc, which will require quite costly work to replace them. How do I fix the problem? - replace the pads with new and good quality ones!
2. Nothing lasts forever
Another reason for the appearance of unpleasant sounds can be elementary wear of the pads, because everything has its own deadlines. Of course, the driver who periodically conducts diagnostics and maintenance of his car at the service station will never allow his pads to wear out to a metal base. In this case, their urgent replacement is extremely necessary. And it is better to do this not on your own, but in a specialized service station, because incorrect installation provokes increased wear of the entire brake pair.
3. We fight dirt
The appearance of extraneous noises during braking can also be caused by the ingress of a stone, sand, dirt or any other abrasive into the brake system. In this case, it is enough to clean the pads thoroughly. It is just as easy to eliminate the squeak caused by moisture on the friction linings (after a car wash, during rain, etc.). To eliminate the problem of skip during braking, the friction pads can be simply dried, including with a series of intensive braking.
4. They will get used to it
Sometimes the appearance of a whistle, squeak when braking a car can be caused by the installation of new brake pads. The same phenomenon can be observed when running in new vehicles. As the "grinding" proceeds, these sounds, as a rule, disappear, since the surface layer of the linings wears off as they are used.
5. Have you washed your car?
After leaving the car wash, you have a squeak when braking - this is a normal phenomenon! This also happens after a heavy rain. Rust has formed on the disks after washing and after several brakes it will disappear, and after that an unpleasant creak.
So that the creak during braking disappeared - it's worth to fork out
Thus, there can be many reasons for the appearance of extraneous noise during braking, up to the reaction of the system to low temperatures, etc. The main thing is to identify them and, if necessary, take urgent measures, because we are talking about traffic safety. When replacing elements of the brake system, of course, you will have to fork out, but not much.
The cost of the pads depends on their manufacturer, car model, other conditions and varies from 300 rubles. up to 1 thousand rubles and higher. The purchase of a brake disc will cost a little more - the price is from 1000 to 3000 rubles. Well, plus, of course, the payment for their installation, which depends on the region, service station, car brand, etc. On average, you will have to pay from 1 thousand rubles.
