I put Porterfield C4's and aluminum slotted rotors on my 84 Carrera. Stops like a race car and no shuddering. Not to hijack, but now I have squealing when the brakes are worn. I have these same pads on my 81 SC with no noise. We've chamfered the pads and roughen the rotors a little. Some improvement, but still unacceptable. Any ideas?
