what material are the pads? Some are more metallic than others & can cause an audible resonance. If brake performance is not impacted, it would be just a personal preference to address it, otherwise, it make stop or fade less over time of being a nuisance. You can try a 200ish grit even scrub followed by a clean wipe down using denatured alcohol on both sides of the rotor to see if it changes any. If it does lessen or eliminates the noise & comes back, it's likely the pad material. If it never returns, then you removed a potential surface contaminant.

Just like rim brakes I've had in the past, with my disc brakes if they start squalling, then I just make sure they are clean with some alcohol and it goes away after a ride or two.

Usually they develop an annoying squeal after riding in the rain. But again, just not worrying about it every moment gives it time to fix itself in a ride or two..

Damn OP, could you maybe make that post a little easier to understand? Try some punctuation every now and then. Like periods at the end of sentences. ... . .

maybe don’t comment if u don’t understand I’m not expert on writing/spelling I try my best to word etc and I understand if no one comments because then it means my wording all wrong but then get daft people like u with your comments

Front disk brakes are the king of squalling. I was only able to stop the noise by using a heavier built rotor. I now use an ebike rated rotor.

I'm trying to help you out. You don't need to have a degree in creative writing, I'm talking about middle school knowledge.

Which is more important? Your brake issue or rebuking someone that you feel impugned upon you wrongly?

I always make sure to clean the rotors before using new pads, then make sure to bed them in. Everyone has their own method, but I still believe that fast to hard and long braking works best for me. Good luck

This is not how you bed in new pads. 15-20 hard decelerations (do NOT stop all the way) with minimal time between each braking event. You need to get them hot to deposit pad material on the rotor. This could be why they're now making noise. You can scuff the surface of the pads w/ sandpaper and do the same to the rotors and then re-do the whole process.
