The brake quiet works great, but you are suppose to use it when you are doing a brake job.(everything new) If the pads are not tight in the caliper, they can get hot and cause the squeaking. You can try, this take a block of wood, staple a piece of coarse sand paper to it, and scuff up the pads. You can also take a fine metal grinder disk and hand scuff the rotors.
