Noise in dash when braking
I just recently purchased an 02 Suburban w/ 45k. This is my second 02 and my first was quiet and no issues, but this one has what I hope is just the “Piston Slap”, noisy vent fan and a noise in the brakes. When I press on the brakes a noise comes from what seems to be in the front middle of the dash. It’s in between a whine and a squeal and get louder the hard you engage the brakes. Light braking doesn’t make any noise, but anything beyond slightly aggressive makes the noise. I believe it is on the inside of the firewall in the center of the vehicle under the dash, but could possibly be under the hood. Any ideas?

Everything seems to be fine, it drives nice and no vibration or pulls in the wheel, it just has a noise when engaging in the brake. I may not be able to add much more info, I strongly believe it is coming from in the dash. It may be a something loose in dash that squeaks shifting forward and is noticed when breaking. I’ll keep looking, let me know if anyone has any additional comments.
