The reason for the beeping
Not so long ago, carts drove through the streets of cities, creaking deafeningly with unlubricated axles. This was due to the fact that the wheel hub “welded” to the axle every now and then, and then abruptly broke off, causing a creak.
Much the same thing happens in modern cars, when the brake pads stick to the disc or drum for a split second during braking and then break back.
The axles of the carts were periodically lubricated and the creaking disappeared for a while. But is it possible to lubricate the working surfaces of braking mechanisms? Oil – no: you are without brakes. But you can’t let the pads oscillate freely. In practice this is done in different ways.
Metal anti-cracking pads are installed on non-working surfaces and chamfers are made on workers. In the latter case, the working area is reduced, but the developers deliberately go for it, shifting the resonant frequency of oscillations to the region of the inaudible range.
Another technique is to make one or more slots on the working surfaces of the pads. Sometimes, to dampen vibrations, a special plate is installed, which is attached to the back of the block with legs. Several brackets are used for the same purpose on some structures.
Many brake pads are equipped with acoustic wear indicators: in these cases an unpleasant squeak when braking is a signal to replace them.
In the front brake pads for rear-wheel drive VAZ models, it is structurally impossible to install “beeps” warning of wear limit. Therefore, in order not to damage the discs, it is better to replace the pads prophylactically by providing reliable and inexpensive products under the Za Rulem brand.
All in due time
Worn pads may also squeak. In no case do not delay the replacement: such pads no longer slow down. In addition, they cause a deformation of the pistons extending from the cylinders to the limit. Therefore, do not wait for the maximum output of the pads – it is better to replace them proactively, then they will not make any sound.
Brake pads designed for VAZ-2108 are suitable for use on modern front-wheel drive vehicles from AvtoVAZ to Lada Granta. For cars with ABS and ventilated discs, cheap and at the same time reliable, wear-resistant and non-cracking pads under the Za Rulem brand are quite suitable.
Matter of choice
Given the sanctions and the total shortage of spare parts, the choice of brake pads has become difficult. A large number of counterfeits under well-known brands have appeared on the market. Recall that almost all foreigners have left the Russian market and do not deliver their products to us.
If you are lucky, you will buy a cheap “noname” in the guise of expensive foreign pads. Most likely, such pads will start to make noise, because their friction mixture contains too many iron shavings.
Such pads will brake harder, but the brake discs will wear out quickly, resulting in high expenditure. In addition to noise, they will overheat and brake poorly, which is dangerous!
For rear-wheel drive VAZ cars, the “Behind the wheel” rear brake pads are perfect. They are distinguished by a high-quality adhesive bond of the liner to the base and precise geometric dimensions.
Therefore, when replacing brake pads, we recommend paying attention to products from domestic manufacturers. In particular, we note that brake pads “Behind the wheel” have appeared on the market, which are distinguished by high quality and reasonable price.
