"Squeal is a complex phenomenon which depends on the friction property of the pad and the rigidity of the system along with some other variables. New KoolStop shoes are some what more prone to squeal than many others because of the raised rear corner. If that's filed (or worn) off they squeal much less." FBin NY
I grind off the rim rake (the raised end of the Kool Stop pads) before I mount then all the time. I, too, find that a pad without the raised end is quieter. I also will file/grind the end edges of the pads' segments sometimes to further try to shut them up. Andy.
