I hate squealy brakes. I have struggled with them on my IS300, have swapped out pads all new hardware.
I thought I had it kicked with the latest change of pads and hardware. But it came back. It is fairly mild when I gently apply the brakes, but goes away when I push a little harder.
Read about rotors getting glazed and causing squeal. I mostly drive like an old man, brake early and gently. Am I glazing my rotors and causing my own problems?

Are your pads wearing evenly? You could have some bad slider pins on the brake itself? I think those could cause some squealing

The pads do wear evenly, everything seems to be working as it should. I scuffed the rotors with some fine sandpaper yesterday when I was swapping to the summer tires, so far so good, but only about ten miles since then.

Did you coat the backside of the pads (and any shims ) with Brake Quiet or similar?
I’ve always associate brake squeal with very high frequency vibration more than anything. Could be wrong — I’m pretty liberal with my anti-squeal stuff.
Yesterday (see all the blue stuff on the towel? Overspray):

Did you change to a different pad compound? I’ve always had a rough time chasing down brake squeal.

Make sure the pins are lubricated, the pad “ears” move freely in the channel and use that quiet stuff on the back of the pads. Squeal is usually caused by something vibrating and that is caused by either metal on metal binding or something loose that’s rattling.

Are you following proper bedding procedures? I follow what Powerstop recommends and I’ve never had a squealing problem. https://www.powerstop.com/brake-pad-break-in-procedure/

Thanks, the pads came with pre-in stalled anti-squeal shims, but wouldn't hurt to add a little more goop, I know I have a tube somewhere in the shop.

Supposed to have it on the shims already, but I could add more.

I did the heat them up and cycle th em through as described in the article. No squeak for the first couple weeks, then it started and pretty persistent, I scuffed the rotors, and it stopped again, will see for how long.

It would be interesting if repeating the procedure eliminated the squeak. That might indicate that your braking habits are the source of the problem.

I did try that, went away for a very short time, then came back.

Well, I suppose that’s some evidence that it might be your driving that’s causing it. If the other suggestions don’t work, then you might have to reconsider your driving habits. If you are resting your left foot on the brake pedal, that might be a cause too. Even lightly resting your foot there activates your brake lights and pushes the pads against the rotors.

Braking gently wears out the inner pads and causes vibration because it's not enough pressure to move the caliper and squeeze the out side pads
