so i hear some weird scuffing sound coming from the passenger side , not sure what it is. the guide pin are not sticking, because i greased the hell out of them, but read that the retainer clips actually have a left and right hand side of putting them on? i can stick my finger between the pads on the driver side, but not on the passenger side. one has more space between the caliper and the rotor.
passenger—^
driver —-^

New pads will drag on the rotor until it all gets centered up from being driven. It may take a while. Semimetallic pads usually make the most noise in that regard.
Looking at the picture of the passenger side, it looks like the pad is coming in contact just a bit with that rust ridge on the rotor. that will definitely contribute to the scratching noise you hear along with the pads being new. once the pads wear in things should be quieter.
They all make a scrapping sound for a while until they set in even if the pads and rotors are new.
Its not like the drum brakes where they get match shoes to drum.Did you have the rotors turned when you did this? Pad slaps are a problem child for making noise. Also, as Wokko pointed out some noise as they get all seated in and bedded is par for the course even when new.
sorry for not updating sooner. the pads got quiet after some time of driving, but then it came back again. i noticed that when it did go away the rotor was clean and shiny, and when the scrapping noise came back the rotor was dirty. i kept cleaning the rotor with brake cleaner and for a couple of blocks it would actually not be there. then as soon as i used brakes it came back. hmmmm. also the gap/clearance between the rotor and caliper is very little. The driver side is fine and has plenty of clearance and no scrapping noise. Also it’s always clean and shiny. kinda dumbfounded right now. i changed the brake retainer clips to see if that was the problem, but did not change anything.
as a warning , i have Wagner Brake parts . i got mine from rock auto. i ordered a set of rear brakes about a year ago, so when my rear brakes would finally wear off i would have a set in hand. The problem was that the brake retainer clips did not fit the rear calipers. I couldn’t get them to sit flush even if i really pressed hard on them. I Called rock auto and was informed that the Wagner company tweaks their products to fit multiple cars.
Other than the little bit of rust on the rotor the only thing I can think of is if your pad has a groove in the centre of it try cleaning it out and see if the noise goes away. I find that to be the problem on my van where brake dust builds up in that groove and causes noise. I just use a pick or a flat screw driver and scrape all the stuff out.
