These are great pads if you use them on new or newly machined discs. and cause noise. I had 1 new rotor and another one that was "decent" and this one was noisy, I replaced it with a new one and the noise is gone. So if you're having trouble, make sure you're using new or lathed rotors. The stainless steel pad for the guide calipers is quite thin. Make sure your calipers are free of rust or road debris or they will not fit properly. I took a small chisel and a hammer and pounded on the edges until all the rust was off, then used a coarse wire brush on the drill after one failed attempt at installation and no more installation problems.
