Just installed pads and rotors (non-brembo) and i'm in a little pickle.

Once the brakes warm up, im getting a loud squeal under light brake pressure from the right rear wheel. It wont squeal or it will quickly squeal under heavy braking. It's also worse with speed, not so bad when i'm moving slow. It will not make noise when the brakes are still cold. Once it starts, it will not go away.

I reinstalled the shims after cleaning them and greasing them up, cleaned the pad retainers, and piston and piston boot area. In fact, I've now done it twice. I also bedding in the brakes properly.

I can't for the life of me figure out what's causing the squeal

What kind of pads?
Are you using anti-squeal compound on the back of your shims (I assume this is what you mean by "greasing them up"?
Describe your bed-in procedure.

Maybe they have to break in. I just recenty changed my front pads and they squeeled for a couple hundred mines but now it doesn't do it anymore. I used OEM Nissan pads btw.

Yeah, im using anti squeal. The pads are axxis deluxe. I've had pads make noise before, but it's not a cold pad/track pad squeal that goes away. Once the pads warm up, it doesn't go away and gets really high pitched from the one wheel

I did the standard bedding according to stoptech, which is also the same off the Zeckhausen website.

Did they squeal during the bedding process?

grease back of the pads. id bet my pink slip on that being the solution

That has worked for me every time.

No. They were fine. They started making noise after they were bedded in and cooled down.

It's already been done as stated in my post.

Interesting, as it seems you have performed the proper installation and bed-in process. Did you notice the grayish/blue film on the rotors after performing the bed-in procedure? Also, did you scrub your rotors with mild soap and water prior to installation? Not sure if this would really affect squeal characteristics, but I read it can affect transfer of pad material to the rotor.

I would say another, more aggressive bed-in procedure (they aren't aggressive pads as you mentioned, but might be worth a try), or just slop more anti-squeal compound on the affected pads and hope for the best. A long shot would be a slightly imperfect pad contacting the inner portion of the rotor resulting in friction and squeal, but doubtful though.
