A very common problem for motorists is the creaking of the brakes of their cars. Even if it's brand new, pads can make an unpleasant harsh sound. This is not at all a sign that the malfunctioning of the brake system has begun . A sharp sound causes irritation to motorists. However, the fact that the brakes creak does not affect the system’s overall performance. The cause of the unpleasant sound that the pads make is very difficult to determine. That is why the bulk of drivers prefer to contact the car service in order to replace the parts of the brake system.
What are the reasons that the brakes creak? Basically, this phenomenon is observed due to poor material used in the manufacture of pads. Even when they are completely new, their quality may be desired. Such a shoe may damage the brake disc. It will have to be replaced as a result. In this regard, in the event that you find that the pads installed on your car are fake, replace them with the original ones.
There is another reason brakes creak. It lies in the incompatibility of pads with system disks. Various materials used in the manufacture of these parts can make unpleasant, harsh sounds when in direct contact. This is due to metal incompatibility.
The brakes also creak due to running in new brake pads. If the reason lies in this, that after two or three days the unpleasant sound will disappear itself. The fact is that the upper part of the pads is covered during production with a layer of special impurity. It is he who causes the creak. After erasing the layer, the unpleasant sound disappears. If you want to remove the creak as soon as possible, then brake sharply at a speed of one hundred kilometers per hour. The similar actions done several times contribute to the heating of the pads and the burning out of the layer applied to them. There may be times when this does not help, and after some run of the car, disc brakes still creak. Then replace the pads.
The cause of an unpleasant sound in the brake system may be the ingress of water or dirt into it. In this case, it is recommended to clean the pads or wait a few days, during which the creak should disappear. Sometimes an unpleasant sound in the brake system appears when the outside temperature is negative.
The creaking and whistling of the pads may indicate wear. The metal plate of a special indicator in this case begins to come into contact with the brake disc, which is the cause of unpleasant sounds. In this case, the replacement of the pads should be made immediately.
Disc brakes are a complex mechanism. It works under conditions of constant intense load. In this regard, the brake grease must meet certain requirements. To service the pads used:
1. High temperature extreme pressure pastes. They are used in the processing of staples, anti-creak plates, as well as the reverse surfaces of the pads.
2. High-temperature greases used for surface treatment of caliper parts (piston edges, bushings, bolts, pins, oil seals).
3. Universal lubricants. They are used to service moving parts of the caliper, including plastic and elastic.
