I replaced the NIBK pads, which, from the moment of installation, emitted a rumble and rattle "metal on metal" or "sickle", as if they had already worn out to zero. The discs are even - I checked, however, when braking, the pedal vibrated. After replacing with Sangsin, all the jambs are gone - this is already a plus). Has some pros: Regular normal pads. They do what is required of them. The movement is mainly in the city, on the highway is also quite acceptable. Haven't tested it at superspeed. The mileage is still small - maybe they will still get used, or maybe some jamb will come out. Got cons: The friction lining gets dirty, although it is possible that this is not a drawback. The lasts I have purchased are labeled but do not have the HI-Q name even though all the images on the web have it. The complete lack of up-to-date information on how non-counterfeit products should look and be labeled.
