Опель астра H замена передних колодок, сухие направляющие

The front guides on my car are dry, but I'm lubricating them for the sake of experimentation. It turns out that if you don't lubricate them, the guide rubber seals need to be replaced frequently, but we live in Russia, and no one will change them for 100 years. I've done this experiment on my car and lubricated them several times, and I haven't found anything wrong with it. But if you want to follow the instructions exactly, don't lubricate the guides. I installed the cheapest brake pads, or at least one of the cheapest, and they don't squeal or ruin my old rotors. The brakes are excellent! The entire process is in the video.
