I got some work done a few weeks ago and for a couple weeks everything seemed fine and there was no squeaking/squealing sound.

I got new rotors/brake pads put on, they didn’t add brake fluid citing I didn’t authorize it which I guess I was just going through the no’s when they were telling me about cabin filter or air filters I needed. I’m curious as to why the brakes are screeching after a couple of weeks. I tried going to an empty lot down the road to recreate it but it doesn’t seem to happen unless I’m above a certain speed and or hitting the brakes a certain amount.

Now I’m getting lots of squeaking/squeaking/screeching sound lost getting the work done. Any advice is welcome!
