I’m having a really nasty brake squeel mainly when I brake lightly to a stop and mainly when the brakes have some heat in them. I have tried replacing the pads and resurfaced the rotors and the exact same noises are still there which was really annoying and unfortunate. Being that the new pads and resurfaced rotors are making the exact same noise as before, I don’t think it’s the new pads causing the noise and I’m not really sure what else could be the issue. If anyone has suggestions that would be appreciated. I have the grey brembos for reference.

Squeal is caused by metal to metal contact. That happens with inadequate lubrication of the pad to caliper contact.

Did you put anti squeak stuff between the pads and calipers?

Caliper pistons still good and not seized?
Had jurid pads Zimmerman rotors. Now I’m at hawk 5.0 with same rotors but resurfaced. I applied a thin layer over the backing plate of the pads where the pistons contact it.

Also mainly happens when the brakes get warmer.

I could add a video of how it sounds am not sure how to upload it here. It sounds like it may be happening on one spot of rotor though.
