Replaced rear rotors and pads, worked great for the first couple of hundred miles all of a sudden they're squealing like mad!!! Calipers aren't hanging up, e-brake releases fully, I took the calipers, rotors, pads off and the pads were glazed over like a mirror!!! Sanded the pads down, lightly roughed up the rotors put everything back together, a couple of hundred miles later, squealing like crazy when almost to a dead stop, I'm thinking cheap pads, I got them at Autozone, what pads should I be using to eliminate this crap?!?!? shoot Thanks for your help in advance!!!
