Bought the posi's based on overwhelming positive feedback. Installed them last week. No brake dust but noticed today that they squeek at very slow stopping speeds

WTF?
I have beded them not as hard as they suggest but at least five times. Any suggestions.
Also, The place I had them installed has done allot of work for me but they would not warranty against noise or vibration. He did say that he really likes the pads and has installed them on several vehicles.
