Why a new block is erased “to zero” and the rest is like new

It is not unusual for a driver to suddenly notice strange things after replacing brake pads. Already after 5000 km of driving, one of the consumables is erased

This problem is reminiscent of a nasty creak and rattle. It causes understandable bewilderment from the driver, as the braking system has been serviced quite recently. Yes, and outwardly everything looks decent: no crime. But a closer inspection reveals that one of the pads, which is located on the inside of the disc, urgently needs to be replaced. However, just going to the store and buying new parts is not enough. It is necessary to understand the problem, because ignoring it will lead to the same thing happening with the next purchase.
There could be several reasons for this problem. Say, poorly lubricated and thus jammed caliper guides. This often leads to serious wear and tear. But what if they’re okay?
Then you need to check the serviceability of the caliper piston. As a rule, it fails when a small sealing gum that protects the same piston from external influences breaks. Dirt and water begin to get underneath, stimulating corrosive processes.
As a result, the mechanism stops retracting after braking, and the block remains pressed against the disc most of the time, only occasionally moving away from it due to vibrations. This can end badly: the rubbing surfaces become very hot. It is worth driving through a cold deep puddle, as the “brake” will lead. And in the worst case, it can break.
But few people pay attention to the conductors of the pads themselves. And there is a nuance. On many machines, metal plates are used as the same parts that do not rust. Therefore, the “ears” of the pads move along them effortlessly. But some models don’t. The block “walks” along the cast-iron caliper along the seats machined under it.
So it turns out that the dirt flying off the road gets into the “grooves”. As a result: the consumable “freezes” in one position. It is clear that this usually happens from the inside. Because it is she who is subjected to strong sandblasting. Especially if there are no protective shields.
What to do in this case? It is necessary to disassemble the brake mechanism, clean it from dirt and rust. That is the only way the problem will go away. And it is better to perform such procedures on every APK.
