First time brake job! Please help! Minor squeal

Hey all I am kind of new at this just tryinn to learn - Me and a friend changed just the front brake pads (about 50$ ceramic)about a week ago . This was the first ever brake job done for the car so I assumed the rotors were fine . We made sure it was greased up everywhere it was supposed to (Didn't replace or turn them) so since then my front brakes have been terribly squealing only when I lightly apply pressure on the brakes , but goes away when pressed down harder. I realized I should have probably changed or turned my rotors after I already drove with the new pads on the old rotors for about a week so it's probably too late now. I am just wondering whether this noise go away eventually (what I initially figured it would) from the pads perhaps wearing back into the old rotors ? Or am I better off not waiting for this because the noise won't to away and I should just change the pads again along with the rotors!?

Did you use any Copper Paste on the back of the pads and sliders?

They were 50$ ceramics , I tried going for the nicest brand for the car, forgot exactly what brand. not sure if it's like same as original pads for the car , but whichever were the higher quality pads at the advanced auto parts store under my "make model year" as they look it up

Ceramic pads are a little louder when cold and not warmed up. On your next long drive see if they quite down after braking a few times. Also they should stop squealing after you bed/brake em in.

Yea it's definitely not the cold I don't think , living in south florida where it's so not most of the time lol but I also researched before what I could and did try the braking / bedding technique trying to speed up brake hard the whole nine yards. It's already been a week , not sure how long it takes to brake them in but it's still squealing as it did on day one only when I apply light pressure on the brakes slowing down as i press harder it goes away immediatly. At first I was cool with it thinking it'd go away or start to fade away but it's not at all. I guess maybe I should wait a little longer and see what happens before I replace the pads again along with the rotors this time, as I should have done orignally. , thank u vm for the quick replies by the way

You didn't put any grease on the rotors did you?? Did you clean them with brake cleaner? Old rotors will have tiny ridges in them from your old pads so it may just be something to do with them rubbing a different way. My ceramics are louder than normal sintered metal. Good luck!

Ha didn't think this thread was still up , well about a week ago after not beig able to stand the squeal, my second try I replaced the rotors with wearever(as I should have in the beginning or at least turned them) as well as the pads again I went with wearever because I didn't want to use the newly worn pads I just bought two weeks ago when I tried the first squeaky brake job also wanted have same companies pad and rotors, luckily I put the newly worn pads I had just bought two weeks ago in the wearever box i picked up today and returned them to aap! All in all so far so good(day 6) I'm extremely satisfied, glad and proud to say no squeaks , brakes are perfect, smooth.

This is an easy fix OP. Just take some 80 grit sand paper and place it on the floor. Next, take each brake pad and rub it back and forth on the sand paper till you remove all the dark or shiny glaze. Next, sand around the edges of each brake pad until they are rounded. Now install them and enjoy the quiet.
