I think u should quit with the "Pads squeal".
If everything has been installed correctly, and has been done according to how it should be then pads wont squeal.
FYI, nissan include copper grease a part of the shim kit. I used it and have never had any squeal or noise from the rb74's i have in their now. These are a slightly more expensive pad than bendix crap too, and i only use em on the street.
Ive had my callipers rebuilt, the new rotors machined, new pads installed, new shim kit and everything is quiet. Do a have arse job and just slap in new pads, then dont do the "bedding in" period (Yes this means matching the surface of the pad to the rotor, or removing any compound from the pads manufacture) and u will have problems.
