I replaced a fairly new set of aftermarket pads that squeaked like crazy. I tried all the solutions to stop the squeaking, didn't work. So I decided to go with OEM quality ceramics. I should have paid a few dollars more and gotten it done first. These pads are absolutely silent, very smooth. Exactly what I needed. These pads have what it takes to replace small wear surfaces and being ceramic they will handle my SUV's towing and braking up hills.
