Most brake noises are caused because the two friction surfaces aren’t happy with each other, or the brake friction surfaces weren’t properly broken in.
When doing a brake job, you want to make sure the replacement components meet or exceed but not deviate from the OEM specifications. So if you use a ceramic friction material where a semi-metalic is spec’d, that can cause brake noise. Or if the proper friction materials are replaced, but the proper break-in proceedure wasn’t followed, this can cause brake noise.
